Alors que les SSD dominent le marché en matière de performance, Seagate continue de miser sur les disques durs mécaniques pour le stockage à froid dans les centres de données. Le constructeur américain vient d’annoncer la livraison des premiers modèles de 40 To, posant les premières briques de sa feuille de route vers 50 To à l’horizon 2028…
Seagate 40 To
Le nouveau EXOS M 40 To repose sur la plateforme Mozaic 4+, évolution du Mozaic 4. Il intègre la technologie HAMR (Heat-Assisted Magnetic Recording), qui consiste à chauffer localement les plateaux à l’aide d’un laser pour augmenter la densité de stockage tout en assurant la stabilité des données. Ce disque regroupe 10 plateaux de 4 To chacun, dans un format 3,5 pouces standard, illustrant la volonté de Seagate de repousser les limites physiques sans bouleverser les formats actuels.
Jolie prouesse, mais quelques retards
En mars 2021, Seagate nous dévoilait sa feuille de route ambitieuse. À l’époque, il annonçait l’arrivée des disques 30 To pour 2023, 40 To pour fin 2024 ou début 2025, 50 To pour 2026… pour atteindre 100 To en 2030. Aujourd’hui, ce planning a été ajusté. L’entreprise ambitionne de proposer un disque de 44 To d’ici 2027, puis 50 To en 2028.
Ce décalage s’explique par la complexité technologique du HAMR, qui allonge les cycles de qualification et de production.
Marché de la très haute densité
À ce jour, le HAMR est la seule technologie industrielle capable de dépasser la barre des 40 To. Les concurrents explorent d’autres pistes :
Western Digital mise sur des solutions hybrides comme OptiNAND ou ePMR ;
Toshiba privilégie le MAMR (Microwave-Assisted Magnetic Recording).
Pour Seagate, ce choix technologique vise un marché spécifique : les fournisseurs de services Cloud, les DataCenters à grande échelle et les infrastructures AI/Big Data, où les volumes colossaux importent plus que la vitesse d’accès.
En synthèse
En livrant ses premiers disques durs de 40 To, Seagate pose la première pierre d’une ère où la densité prime sur la vitesse. Si l’arrivée sur le marché grand public est encore lointaine, l’enjeu stratégique est clair : consolider sa position dans le stockage d’infrastructure et ouvrir la voie à des capacités toujours plus élevées.
Prochaine étape ? Une industrialisation en 2026, suivie d’un passage à 50 To en 2028. Une course où la prudence technique rime avec ambition.
Synology Explain WHY They Changed Drive Support and Verification in 2025 NAS
During a recent visit to Taipei for Computex 2025, I took the opportunity to visit Synology’s headquarters and speak directly with company representatives about one of the most discussed and divisive topics in the NAS community today — the company’s increasingly strict stance on hard drive compatibility. With the rollout of Synology’s latest generation of hardware, users have been met with significant limitations on the use of third-party drives, prompting concern over reduced flexibility, potential e-waste, and the future direction of Synology’s hardware ecosystem. This article provides a can overview of that visit, beginning with the HQ tour, but mainly it is about putting several big questions users have about the brand’s change in support of Seagate, WD, etc on their 2025 devices.
Four core questions — based on direct community feedback — were put forward, addressing the motivation, risks, and future implications of Synology’s current drive support policy. Each answer is presented exactly as delivered. Note, this article is not sponsored by Synology and they have no control over the editorial stance and output! For users, partners, and industry observers alike, understanding these policy shifts is essential for making informed decisions about Synology systems moving forward.
Touring the Synology Headquarters
The Synology headquarters tour took place during a coordinated visit arranged alongside the Computex 2025 trade event. Approximately 30 to 40 individuals were in attendance, a mix that included official Synology partners, resellers, independent media, and technology commentators. The tour began with a structured company overview presentation outlining Synology’s operational history, business units, and market positioning.
While much of this information was familiar to long-term observers, it served to reinforce the company providing integrated storage and data management solutions. The presentation also included a brief overview of Synology’s global distribution and the evolving structure of its enterprise product lines.
Attendees were then guided through various areas of the facility, which covered several floors within a shared building. Synology does not occupy the entire structure, but the portions shown during the tour were substantial, comprising office sections, collaborative workspaces, logistics coordination areas, and support-related operations. Notably, many desks were temporarily unoccupied due to staff presence at Computex’s Nangang Exhibition Center.
Nonetheless, the offices remained populated with active terminals and systems undergoing live testing.
A significant portion of the tour focused on the environmental and durability testing facilities, including designated zones for acoustic profiling, thermal analysis, and dust resilience. The diversity of units being tested suggested coverage across multiple device classes, including both rackmount and desktop models.
The most extensive portion of the tour was the dedicated test and burn-in area. This floor was almost entirely devoted to long-term performance and diagnostic evaluations. Numerous Synology NAS units — some dating back to the early 2010s — were in continuous operation, either running synthetic workloads or undergoing compatibility assessments with the current DSM operating system.
The presence of so many legacy devices in active testing underscored the company’s emphasis on software longevity and cross-generational hardware support. However, it also provided a contrast to Synology’s new strict verification policies, especially given the mixed hardware environments visible during testing. The tour was led by ZP Kao, Sales Director at Synology, and Chad Chiang, Regional Manager for the UK and Germany, who offered clarification and responded to several direct inquiries during the walkthrough.
Why Has Synology Changed Its HDD Support Policy? Questions and Answers
Questions I put to Synology about their change in policy regarding verifying and supporting drive media being used on their 2025 and later series of NAS devices. I based these on the comments and suggestions from videos on the YouTube channel and comments on previous articles. I am under no illusions that these changes by Synology in their drive support policies have financial justifications (ranging from Support efficiency and it’s financial overhead, to the simple profitability of prioritizing their own labelled firmware optimized storage media choices over those of other brands), but I wanted to know if these were the only reasons for this? What other reasons could Synology provide to support this large and unpopular move. Thank you once again to Chad Chiang for taking the time to answer these questions.
Note – for a better understanding of the current DSM Support of Unverified media, as well as test scenarios detailing each setup and how DSM handles it, you can read it HERE in my Test Article.
How has the verification process changed for which drives you can use on Synology systems moving forward? And are there drive options from WD and Seagate currently undergoing support verification?
Answer – At Synology, we constantly reflect on a core question: Why do people choose a NAS? We believe the answer lies in the need for secure, reliable, and hassle-free data storage. This belief has guided our mission for over a decade. When analyzing our support history, the data clearly shows that systems using Synology-branded drives experience 40% fewer issues compared to those with third-party HDDs. This insight underscores the importance of using thoroughly tested drives. As for which third-party vendors are currently undergoing drive verification, we’re unable to disclose details. For the most accurate and up-to-date information, we recommend reaching out directly to the respective manufacturers.
The response positions Synology’s verification changes as a reliability-focused initiative and smooth platform running as the chief reasoning for them, referencing internal data that suggests a 40% reduction in support issues when Synology-branded drives are used. However, as mentioned previously, the statement does not provide supporting metrics such as sample size, timeframes, or specific failure modes, making it difficult to assess the scope or significance of this claim. I do not doubt that it is true, but without the X/Y and details of how this result was achieved, we are only getting half the story here. The policy shift is framed as a precautionary measure aimed at minimizing user disruption, but the absence of transparency regarding ongoing verifications with WD or Seagate limits clarity for users seeking alternatives – which is why users are seeing this more as a means for the brand to increase profitability in the 2025 series as a bundled utility purchase – not as a means of system stability.
Ultimately, discussing the technical standards or benchmarks involved in the verification process in paramount here. It largely confirms that responsibility for future third-party compatibility lies with the drive manufacturers themselves, effectively shifting the onus of transparency to them. While it is understandable that Synology might want to mitigate support complexity, the lack of specificity about how the verification criteria have evolved or what steps vendors must follow leaves key questions unanswered for both users and third-party storage providers. I reached out to representatives from Seagate and WD to see if they could elaborate further on this new media side verification process with their respective NAS/Server class media – neither was able to provide further details at this time.

Users are able to migrate existing storage arrays that feature Unverified/unsupported drive media in previous Synology systems into 2025 Plus series devices and still use DSM services – however once they do so, they are unable to use the same model ID of drives to perform RAID recovery, RAID expansion or introduced a hot spare, unless that drive is on the verified drive list. Why is this?
Answer- Advanced operations such as RAID recovery, expansion, or hot spare assignment are technically intensive and carry a higher risk of data loss if inconsistencies arise. Drives that haven’t been validated through Synology’s verification process may behave unpredictably under stress, impacting array stability or performance. For this reason, support for these functions is limited to verified drives—a precaution designed to safeguard user data and maintain long-term system reliability.
So, this answer outlines Synology’s rationale for restricting critical RAID operations on unverified drives and It emphasizes the increased risk associated with advanced storage operations, particularly when performed on drives that may not have been tested under stress or fault conditions. The justification focuses on data integrity and system reliability, suggesting that verified drives have undergone stress testing scenarios that others have not. However, the lack of granularity in what defines “unpredictable behavior” makes it difficult to independently evaluate the severity or frequency of these issues. Much like the statistics point earlier, this seems a remarkable stretch in terms of reaction to what many users would consider a very, very low % risk factor. Equally, though there is an argument that some drive media is less suitable for NAS usage (eg the WD Red SMR drives, desktop single drive use media like Seagate Barracuda and high power draw HDDs/SSDs in some cases), these make up a very small % of drive media in the market and using this as a reasoning to effectively bar the continued support of drive media that has been supported/used in Synology server use over the last 2 decades to prevent RAID recovery and Expansion in the latest gen for those carrying them over seems insane overkill.
The policy effectively limits upgradability and flexibility in mixed-drive environments. While it is technically reasonable to restrict risky operations on unvalidated components, the ability to migrate but not expand or rebuild a RAID introduces a half-measure — allowing users to enter unsupported configurations while restricting them mid-cycle. The result is a system state that may appear functional at first but ultimately lacks key functionality unless users conform to the verified list. For long-term users upgrading from older systems, this shift can lead to unexpected limitations without adequate warning, particularly in small or home office deployments. The messaging has been poor and though I made a video about these limitations (embedded above), there is practically no other clear and transparent information about this online (with incongruous detailson the Synology Knowledge base that could stand to be a lot clearer and louder).
HOT TAKE, and hear me out – If Synology do not allow support of RAID repair/Expansion on drives that have been migrated over from older NAS systems where the drives WERE originally supported (unless they use 2025 verified drives) because of reasons of stability, I have a somewhat extreme suggestion. As unpopular as it might have been, Synology should have just BARRED the support of migration from older generation Synology NAS devices with unverified drives entirely. I personally think they should have allowed for RAID repair/Expansion of unverified drives, but if they are going to pursue this for reasons of system stability, they should have committed to this fully and not allowed this grey area with migration. As it just looks bad for the brand, as means of ensuring people can upgrade/remain in the ecosystem, but then have limited scalability when those older drives require replacement/growth.
Were pre-populated Synology NAS devices considered, given the strict verified support stance that this new Synology hardware generation contains?
Answer – Regarding pre-populated NAS solutions, there hasn’t been significant internal discussion or a formal strategy around this model. As such, I don’t have a concrete answer at this time. The focus remains on ensuring that any storage media used—whether user-installed or bundled—is fully verified to meet Synology’s reliability standards.
Not much to unpack here. It makes sense. I imagine they DID discuss this as an option (as they are already engaging with this with systems like the Beestation), but at least for now, it seems off the table. As unpopular as this might have been, in some ways it could have solved a lot of this friction for some users. Provide the 2025 PLUS series as an empty/enclosure-only solution with similar compatibility as the 2024 and earlier generation – but then also supply several pre-populated options that feature Synology drive media as standard. However, that would be a different discussion entirely (eg logistics, SKUs, viability, ROI by offering this alongside flexible options).
Can you provide example(s) of critical system issues that using unverified drives caused, that were the tipping point for this new strict HDD support policy?
Examples of what stepped up our verification process moving forward:
Performance Issues: Unverified drives may function under light workloads but can suffer serious performance drops (e.g., IOPS decline) under multi-user access or when running demanding services like virtualization, backup, or databases. This can lead to poor user experience or service disruptions (e.g., iSCSI timeouts).
Stability Risks: Without thorough testing, unverified drives are more prone to failures under stress conditions such as unexpected power loss or long-duration file transfers—leading to timeouts, reboot failures, or data integrity issues in high-load or long-term operations.
Compatibility Problems: Drives not validated for compatibility may show unstable behavior with certain NAS controllers, resulting in drive drops, RAID instability, or data access interruptions over time.
Advanced Feature Failures: Unverified drives may fail during operations like SMART testing or Secure Erase, especially after unexpected power outages. Some drives may not respond properly under frequent access or specific command sets, affecting system stability.
Drive Failures Under High Load or Density: Some drives may become unresponsive under high data density or I/O intensity, with issues persisting even after a reset.
The examples provided by Synology highlight a variety of operational issues associated with unverified drives, most of which relate to performance degradation, system instability, or failure of advanced features under stress. These scenarios focus on workloads involving sustained I/O, power fluctuations, and controller-level interactions. In isolation, many of the issues described are plausible for lower-tier or unsuitable drive models, particularly in demanding or enterprise-like environments. That said, that are very low margins (eg 0.01% or lower) when you look at the traditional deployment of many Synology NAS solution in the Plus series. Again though, the scale and frequency of these issues remain unclear. There is no indication of how widespread such failures are across Synology’s user base, nor whether they represent rare edge cases or common occurrences. The examples also apply more logically to enterprise or high-density configurations, whereas the same strict policies now affect all tiers — including two-bay and four-bay systems used by home and prosumer users. Without concrete statistics or clearer thresholds, it is difficult to assess whether these issues justify the breadth of the policy. The policy appears to target potential worst-case scenarios, but may have broader consequences for user flexibility than the risk profile necessarily warrants.
Additional Information and Details from the MyBroadband Article
Further context on Synology’s new drive compatibility policy was provided in an interview between MyBroadband journalist Daniel Puchert (click to read) and Michael Chang, Synology’s Regional Sales Manager. The discussion reinforced many of the points raised during the HQ visit, while also offering additional information into the motivations behind Synology’s stricter approach to drive support in their latest generation of NAS systems. Chang explained that Synology’s primary objective was to ensure product reliability and reduce system-level faults that were increasingly traced back to third-party hard drives. According to Chang, complaints received by Synology often involved third-party drive issues, yet Synology would still be held accountable by users due to their role as the NAS provider. This prompted the company to centralize responsibility and tighten control over supported hardware configurations. While Synology-branded drives are currently the only models certified, Chang noted that other vendors are being invited to participate in the compatibility validation program — provided they meet the same testing standards.
(In the case of the NAS drives) “..because Synology’s product would typically facilitate the usage of third-party hard drives, it would also be the scapegoat for any faults with the entire system.”
“..complaints received by Synology regarding issues relating to its NAS devices were most often caused by faulty hard drives.
“severe storage anomalies have decreased by up to 88%” for hard drive models that have adopted its hard drive compatibility policy, compared to older models.”
“We still welcome third parties to join Synology’s ecosystem and have invited vendors to join our validation program,”
The article also mentioned that Synology-certified drives undergo over 7,000 hours of testing, and systems using those drives reportedly experience 40% fewer failures than those using uncertified media. Additionally, Synology claims that severe storage anomalies have dropped by up to 88% in systems following its compatibility policy. Although Chang confirmed that third-party compatibility may expand in the future, it will only do so under strict adherence to Synology’s internal benchmarks. These statements align with Synology’s position during the HQ tour, further emphasizing a shift toward a closed, highly controlled ecosystem that prioritizes consistent performance over hardware flexibility.
Synology and HDD Support and Verification – Conclusion and the Long Term
My biggest issue with all this is that, almost certainly, we are going to see Seagate, WD, Toshiba and more slow (slooooooooowly) appear on the compatibility lists for a number of the 2025 generation of devices over the coming months. So, what was all this for? The PR damage and likely early sales damage of the Synolgoy 2025 Series because of this change of support I would estimate is going to be pretty substantial – and all the reports and reactions to this online are not going to go away as soon as a Seagate Ironwolf or WD Red drive appears on the support lists. Also, Synology work on these devices for a very, very long time before launch – why is all this happening now – and not before launch. The cynic in me wants to just assume it was pure profitability and that Synology want to maximize profits, and if when this does begin to U-Trun ,that the brand can say that it was the plan all along. But whether that is true or not, the damage to the brand in the eyes of a substantial % of their long term fans is notable, and with many more players in the market (UniFi, QNAP, UGREEN and more) launching new products in Q3 and Q4 – is this all going to be a gamble by the brand that ends up costing them more than just leaving the support status quo where it was? Only time will tell.

‘Used Seagate EXOS HDDs Missold as ‘New – Other Drives Implicated
Now would be a very good time to check any hard drives you’ve purchased in the last 12 to 24 months! Recent reports from popular German news outlet Heise have raised increased reports of refurbished and modified SMART-reported drives being sold as brand new, leading to large concerns of widespread ex-cryptocurrency-burnt drives being sold through trusted business and domestic retailers. Although the scope of the issue seems to be largely focused on Seagate Exos data center-class drives, because of the wide-ranging drives that were used in Chia cryptocurrency mining several years ago, there is an increased likelihood that other large-capacity and high-durability drives should be considered, thanks to the relative ease of firmware modifications and larger quantities of HDDs being resold off the back of 5 year durabilities lines being crossed by the original coin miners!
Reports are now arriving that Seagate Ironwolf and Ironwolf Pro modified/mis-sold HDDs are now also affected. The extent to this is still too early to confirm, but the latest reports from Heise indicate that 8TB and 16TB HDDs have been highlighted.
Further reports from ComputerBase via a community member fanatiXalpha provided further evidence and indications of this via the images from the original article here:
REAL HDD
FAKE HDD
In this video I discuss multiple ways to initially identify issues with a ‘new’ Seagate Ironwolf HDD that do not involve connecting the HDD to a system. Later in this article cover several more methods that require connecting the drive to a NAS or general client system.
Check Your HDDs – Reports indicate used Seagate Exos hard drives are being sold as new, particularly 12TB-18TB models.
Firmware Manipulation – SMART data shows zero usage, but deeper FARM tests reveal 15,000-50,000 hours of prior use.
Widespread Issue – Over 200 reports from buyers in Germany, Japan, Australia, and other regions, spanning multiple retailers.
Crypto Mining Connection – Many affected drives likely came from Chia cryptocurrency farms (2018-2022) and re-entered the market fraudulently.
Tampering in Supply Chain – Drives may have been repackaged and resold by wholesalers and distributors, bypassing Seagate’s official channels.
Retailers & Seagate Respond – Some retailers are issuing refunds/exchanges. Seagate denies involvement and is investigating the supply chain breach.
Verify Your Drives – Use SMART, FARM, Seatools, and warranty checkers to confirm if your drive is genuine. Report suspicious drives to Seagate and your retailer.
What has been reported on the Seagate EXOS HDD Misselling
Earlier in the year, Heise reported that they had received dozens of reports from users who had purchased brand-new, enterprise-class Seagate Exos hard drives, only to find that when receiving the drives, they had scuffs and marks on them that suggested they were used—and used en masse. Further investigation of the hard drives using popular firmware tools initially showed that the drives’ SMART data was indicating little to no power-on usage. However, deeper investigation with deeper drive tools went on to reveal that the firmware had been manually adjusted to hide the tens of thousands of hours that these drives had already accrued in use.
Usage on drives has varied from between 15,000 hours and 50,000 hours, well over five years of deployment and well outside the warranty and workload rating on these drives in most cases. What is interesting though, is that retailers that have been impacted by this, and in fact a wide-ranging number of German retailers, have been highlighted as sources of these drives. However, reported issues span outside of Germany and include claims from purchases made in Japan, Australia, and other parts of Europe.
Fingers are initially being pointed at wholesalers, large-scale resellers, and distributors who supply the traditional retail and e-commerce websites that most users would be eligible to purchase from. Depending on the retailer, and several have already been highlighted in the now over 200 reports submitted to Heise, the returns and RMA process does differ from site to site, but this does appear to be a growing issue that most users will not even realize they have been hit by unless they take the time to investigate the usage data on their drives.
Primarily, Chia crypto farming has been highlighted as the origin of most of these drives, with huge quantities of large-capacity data center drives being purchased in 2018 to 2022, when this emerging and less GPU-centric form of cryptocurrency was being mined. Brands such as Seagate, WD, and Toshiba saw extraordinarily high sales numbers during this period for these drives, and equally, domestic users ended up being negatively impacted by supply shortages and price hikes. It seems that a lot of these drives that have either been abandoned from previously pursued cryptocurrency setups or just simply swapped out for ongoing farming have now made their way back into the supply chain under the guise of being regular, new, out-of-the-box drives!
The distribution channels, wholesalers, and affected e-commerce websites in order to ascertain how these drives have entered the supply chain and to what extent it has happened. They issued the following statement:
“We are taking this matter very seriously and are conducting a thorough investigation. As explained in the previous statement, Seagate did not sell or distribute these drives to retailers. We cannot provide details of the ongoing investigation, but we suspect that these drives are new products that Seagate sold to customers and were later resold by them on the used market. In this case, we believe that the drives were remarketed somewhere in the used market supply chain and resold as new. We recommend that retailers only purchase drives from certified Seagate distribution partners, as purchasing from certified Seagate distribution partners is the best way to ensure the authenticity of Seagate products for retailers and their customers.
Seagate has processes in place to investigate these types of cases, with teams working proactively with our vendors to take action where necessary. Our security team also regularly works with local authorities to take necessary action. Many investigations are initiated based on anonymous tips and reports from partners and customers. These measures are designed to protect Seagate partners and end customers in an increasingly global marketplace.
We encourage anyone who suspects they have received a used drive marketed as new to help with the investigation by reporting the incident to us directly at [email protected] . In addition, customers who have doubts about whether the products they purchased match the claims of the sellers can access our warranty checker tool . Suspicious drives and/or sellers can also be reported anonymously through our Ethics Hotline .
Currently, the bulk of aggregate reporting of this is going through the Heise website, and a lot of the submissions have been done via their anonymous reporting link, so exact model IDs are hard to track down right now. However, the bulk of the reported mis-sold drives appear to be Seagate Exos drives ranging from 12TB to 18TB. As mentioned earlier, however, the original reporting suggests that other drives have been highlighted by users. Realistically, it’s pretty unlikely that only Exos drives are going to be impacted as such. A wide-ranging procurement took place during the peak of Chia cryptocurrency farming, and pretty much any moderately durable, high-capacity hard drive was changing hands quickly at that time. This all does seemingly indicate right now that a lot of these drives are being offloaded with their firmware modified by one or a handful of bad actors, who likely are sitting on high quantities of the same hard drives. However, it would not surprise me whatsoever if over the coming months and years, we see spikes on affected drives outside of the Seagate Exos data center series.
How Can I Check If My Drives Were Mis-Sold as New?
There are multiple ways to check whether the hard drive inside your system, which you purchased as brand new, is actually new. However, the suitability of each tool will depend heavily on the system type and operating system your drive is running on. Seagate’s Seatools application allows you to check and validate multiple data points on your hard drives. However, it is only available as a Windows or Linux client, as well as a portable version. That means Mac users, or those less comfortable with command-line tools, may find it difficult to use—not to mention users who have multiple drives deployed in systems without a suitable GUI or command-line interface for validity checks. Below, I’ve broken down recommended tools and commands that you can use to verify your drives, their power-on hours, and other critical details.
How NAS users can Check and Verify the usage of the HDDs:
NAS users who suspect their drives may have been mis-sold as new can verify their SMART data and power-on hours using various tools. Most NAS operating systems, including Synology DSM, QNAP QTS, TrueNAS, and UnRAID, have built-in SMART monitoring tools within their storage manager or disk health sections. These tools provide essential SMART attributes, including Power-On Hours (POH), Reallocated Sectors, and Drive Temperature. However, in some cases, the SMART data may have been manipulated to show zero usage, making further verification necessary.
For deeper analysis, users can SSH into their NAS and install smartmontools, a command-line utility that provides detailed drive health reports. Running the command:
smartctl -a /dev/sdX
(where X is the drive identifier) will display all SMART attributes, including power-on hours. However, if the SMART data has been reset or manipulated, users can check the FARM (Field-Accessible Reliability Metrics) values for a more accurate picture of a drive’s actual usage history. To retrieve FARM values, NAS users can use:
smartctl -l farm /dev/sdX
This will reveal true power-on hours, drive usage patterns, and whether a drive has been extensively used before being reintroduced into the supply chain.
For those using QNAP or Synology NAS devices without direct access to smartmontools, Seagate’s Seatools (Windows/Linux) can be used by connecting the drives externally via a USB or SATA dock. Additionally, Seagate’s warranty checker tool allows users to verify if their drive was originally part of a multi-drive batch—a red flag that it may have been previously used in a server or data center environment.
How NAS Users Can Check SMART Data and Power-On Hours Over SSH (Including FARM Values for Verification & Integration with Smartmontools)
NAS users with SSH access can perform a deeper, more accurate verification of their hard drives’ SMART data and power-on hours to detect possible tampering. While many NAS systems, such as Synology DSM, QNAP QTS, TrueNAS, and UnRAID, provide built-in SMART monitoring via their web interface, these tools often rely on basic SMART queries, which may not reveal manipulated or reset power-on hours. By accessing the NAS via SSH, users can run Smartmontools directly, allowing them to extract FARM (Field-Accessible Reliability Metrics) values, which are not included in standard SMART logs.
To begin, users should SSH into their NAS and install Smartmontools if it is not already available. On Debian-based NAS systems (such as OpenMediaVault, TrueNAS SCALE, and some QNAP models running Debian Linux), install Smartmontools with:
sudo apt update && sudo apt install smartmontools
On Red Hat-based systems, use:
sudo yum install smartmontools
For NAS systems that do not allow package installations, users can still manually compile Smartmontools or install a Docker container that includes the tool.
Once Smartmontools is installed, running the command:
smartctl -a /dev/sdX
(replacing X with the correct drive identifier) will display SMART attributes, including Power-On Hours (POH). However, since bad actors can manipulate SMART data to show zero hours, users should perform an additional FARM query with:
smartctl -l farm /dev/sdX
Unlike SMART power-on hours, which can be reset, FARM values track long-term reliability metrics stored at a deeper firmware level, making them much harder to falsify. If there is a discrepancy between SMART-reported power-on hours and FARM-reported power-on hours, it strongly suggests that the drive has been used before but was manipulated to appear new.
Integrating Smartmontools into a NAS for Automated Checks
To automate drive health monitoring, NAS users can schedule periodic SMART and FARM scans using cron jobs or integrate them with the NAS system’s notification service.
Create a SMART Monitoring Script Users can create a simple script to check SMART and FARM values for all installed drives and log the results.
#!/bin/bash
LOGFILE=”/var/log/smart_check.log”
echo “SMART Check – $(date)” >> $LOGFILE
for DRIVE in /dev/sd[a-z]; do
echo “Checking $DRIVE…” >> $LOGFILE
smartctl -a $DRIVE >> $LOGFILE
smartctl -l farm $DRIVE >> $LOGFILE
done
Save this script as smart_check.sh and make it executable:
chmod +x smart_check.sh
2. Schedule Automated Checks with Cron Users can schedule the script to run daily or weekly using cron. Open the cron editor:
crontab -e
Add a line to run the script every day at 2 AM:
0 2 * * * /path/to/smart_check.sh
Set Up Email Alerts for Failures To receive email alerts if issues are detected, modify the script to check for critical SMART attributes and send an email if problems are found:
smartctl -a $DRIVE | tee -a $LOGFILE | grep -i “Pre-fail\|Reallocated_Sector_Ct\|Power_On_Hours”
smartctl -l farm $DRIVE >> $LOGFILE
done
# Email log if issues detected
if grep -q “Pre-fail\|Reallocated_Sector_Ct” $LOGFILE; then
mail -s “SMART Error Detected on NAS” $EMAIL < $LOGFILE
fi
By leveraging SSH, Smartmontools, and automated monitoring, NAS users can go beyond surface-level diagnostics and ensure they are not just scraping the same potentially manipulated data, but actually verifying their drives’ true usage history.
How Desktop Windows users can Check and Verify the usage of the HDDs:
Desktop users can verify the SMART information and power-on hours of their hard drives using several tools, including Smartmontools 7.4+, CrystalDiskInfo, and Seagate’s Seatools. The easiest method is using CrystalDiskInfo, a free GUI-based tool for Windows that displays critical SMART attributes, including Power-On Hours (POH), Reallocated Sectors, and Drive Health Status. However, if a drive has been tampered with, its SMART data may have been reset, making further verification necessary.
For deeper inspection, users can install Smartmontools 7.4 or later, which provides advanced diagnostics, including FARM (Field-Accessible Reliability Metrics) values, which can reveal the drive’s true runtime history. To check SMART data, open a command prompt (or terminal in Linux/macOS) and run:
smartctl -a /dev/sdX
(replacing X with the correct drive letter) to view detailed SMART attributes. If the reported power-on hours seem too low or suspiciously reset, users can retrieve FARM values by running:
smartctl -l farm /dev/sdX
This command will reveal the actual power-on hours and potential prior usage, even if the SMART data was modified.
Alternatively, Seagate’s Seatools (available for Windows and Linux) can run extended drive diagnostics, check SMART status, and validate warranty details. Users can also enter their drive’s serial number into Seagate’s warranty checker tool to confirm if the drive was originally sold as part of a batch, which may indicate prior data center or enterprise use.
How Mac users can Check and Verify the usage of the HDDs:
Mac users can verify SMART data and power-on hours using Smartmontools 7.4+, Seagate’s Seatools for Linux (via a bootable drive), and third-party macOS utilities like DriveDx. Since macOS does not provide built-in SMART monitoring tools, users need to install Smartmontools via Homebrew by running:
brew install smartmontools
Once installed, users can check SMART attributes, including power-on hours (POH), by opening Terminal and running:
smartctl -a /dev/diskX
(replacing X with the correct disk identifier, which can be found using diskutil list). If the reported power-on hours appear suspiciously low, users can retrieve FARM (Field-Accessible Reliability Metrics) values by running:
smartctl -l farm /dev/diskX
This will reveal the true runtime history of the drive, even if the SMART data was manipulated to show zero or low usage.
For users who prefer a graphical interface, DriveDx is a third-party macOS tool that provides SMART data, health status, and power-on hours. However, DriveDx does not display FARM values, so Smartmontools remains the best option for deeper diagnostics.
Since Seagate’s Seatools is not available for macOS, users can create a bootable USB drive with a Linux live environment (such as Ubuntu), run Seatools from there, and check the drive’s SMART health and warranty status. Additionally, Mac users can enter their drive’s serial number into Seagate’s online warranty checker to confirm if the drive was originally part of a batch sale, which may indicate prior enterprise use.
It’s important to note that depending on your system, the directory paths and identifiers for your drives will vary significantly. So, even if 100 users all had the same hard drive model, if they deployed them in different NAS brands, desktop OSs, or even external enclosures, the directory paths and device names would be different. Keep that in mind.
Are only Seagate EXOS Hard Drives Affected?
The Exos series drives appear to be taking the brunt of the reporting here. Realistically, if this flood of dubiously classified new drives is true, then the Exos series is definitely not going to be the only drives impacted by this. Moreover, Seagate was not the only hard drive manufacturer that was pumping out large-capacity hard drives at 12TB, 14TB, 16TB, and 18TB during the peak of this particular crypto-mining industry change! I think it is only now, thanks to the correlation of reports by Heise, that any kind of through-line has been found that specifically targets one hard drive brand or model series. At best, it really comes down to the bad actors who are modifying the firmware on these drives having the financial incentive to do so on a larger scale on a different hard drive series that they happen to have their hands on. The modification process of the onboard firmware and SMART data on Seagate drives is largely identical to that of the process on WD or Toshiba hard drives, and therefore, it really once again comes down to a question of correlating reports of these fake new drives all being collected together.
How Has This Happened? How Did Used Hard Drives Enter the Supply Chain?
You might not know, but when you purchase a hard drive from your local retailer, that retailer almost certainly does not directly receive their stock of hard drives from the hard drive manufacturer in question. Ordinarily, hard drives, like a lot of electrical components, have a pre-established supply chain that retailers and e-commerce websites have to follow when selling their goods. With the exception of OEM companies who can buy from further up the chain and cloud/data centers like AWS and Google who can even buy right from the top, there are technically four layers in the supply chain of hard drives.
The first part of the supply chain is the hard drive manufacturer itself, in this case, Seagate Technology, which manufactures the hard drives at one of its production facilities in numerous locations around the world.
The next step in the supply chain is the Regional Distribution Centers (RDCs). These are the hubs where the hard drive brand sends its manufactured goods to be distributed to numerous smaller distribution centers across different countries.
The next step is wholesalers and resellers. Sometimes resellers can also act as direct-to-end-user sales points, but the lines can get blurry depending on the quantity or device in question. Nevertheless, the majority of electronics and consumables (including hard drives) cannot be sold directly from this point to an end user and instead need to be funnelled to the final step in the chain—retail shops.
Which brings us to the final step in the chain—traditional retail outlets on the high street and the e-commerce websites you choose to purchase from. These are the ones you’ll be most familiar with, and unfortunately, a lot of these are the same retailers that end users impacted by these mis-sold hard drives have as their initial point of contact.
The issue is that these used hard drives, which are being falsely marketed as new, have been introduced into the supply chain somewhere between steps two and four. Seagate has not had any involvement in their reintroduction into the supply chain. Somewhere along the line, these used drives were inserted into the system, and that is what Seagate is currently investigating. The retail outlet where an affected user purchased the drive has more than likely been completely unaware that they have been selling used drives as new. In most cases, these drives would have arrived in sealed retail packaging, and the retailers would have been reluctant to open up supposedly new products for testing, as doing so would immediately devalue the product in the eyes of their consumer and business buyer base.
Therefore, it is going to take time for Seagate to find the smoking gun and pinpoint which wholesaler, reseller, or distributor allowed these used drives to re-enter the supply chain.
Is Selling Used/Refurbished Hard Drives Illegal?
The sale of used, data center-grade, refurbished, or officially recertified drives is completely legal. Although Seagate, WD, and Toshiba would probably prefer to see the used hard drive market disappear, selling used drives is not illegal.
Many online retailers, including Amazon and Newegg, actively sell recertified and renewed drives—just as easily as brand-new ones.
The problem here is that these were used drives that were fraudulently mis-sold as brand new—and that IS illegal. In short, this is fraud, and the people selling these drives could be pursued for damages if customers lose data due to these drives failing far sooner than expected. That’s why any drive that isn’t new is required to be labeled as recertified, refurbished, or renewed. This ensures clarity for the buyer when making a purchasing decision.
That said, some sellers intentionally make it hard to determine if a drive is refurbished. For example, a Seagate IronWolf 12TB hard drive sold on Amazon’s “previously owned” listings might clearly state that it’s used—but it won’t mention that it was originally manufactured in 2017, meaning it could be 8 years old and already have tens of thousands of hours of prior use. It wouldn’t be so bad if the manufacturing date was displayed at the top of the listing, but instead, it’s buried deep in the product details. Bottom line: Selling used drives is not illegal. Selling used drives under the guise of being brand new is fraud—and highly illegal.
Is This Seagate’s Fault?
In all honesty, one could argue that Seagate is responsible for selling large volumes of high-capacity, data center-class hard drives to the original cryptocurrency farmers. However, this would be no different than selling the drives to any regular SMB, just a question of large-scale volume. Seagate is not responsible or in any way officially authorizing the reselling of its hard drives under the classification of new storage media. Additionally, the official partners that Seagate chooses to sell its goods through have almost certainly sold these drives with as much authentication between them and the distributors/resellers as possible. It could be argued that Seagate should personally step in at the supply chain level further down the chain to periodically check the health and condition of drives—much like a hard drive secret shopper—but that’s really about it. Right now, as long as Seagate commits to investigating how this occurred and acts upon what they find to ensure that mis-sold drives don’t enter the supply chain again, that’s about as far as I think this can go in terms of blaming Seagate. Realistically, we can’t lose sight of the fact that it is the fault of the bad actors who modified these hard drives in an effort to recover the original money spent on them before Chia farming collapsed. Wherever the entry point was that allowed these drives to re-enter the supply chain, that is what needs to be identified and stopped.
What Should I Do if I Believe my HDD was Missold?
If you believe that the hard drive in your NAS, server, or storage system was mis-sold to you as a brand-new drive when in fact it was heavily used, you need to contact your point of sale immediately. Tools such as Seagate’s own warranty checkerallow you to enter the serial number of your hard drive into their database checker. Regardless of whether your hard drive is still under warranty, it will still highlight whether this is an official drive or not. Additionally, if you purchased a single drive that was sold as new, but upon entering the details into the warranty checker on Seagate’s website shows that this drive was part of a larger batch, this would imply that the drive you purchased was originally included in a larger server system previously—not unlike how a food or drink product is labeled as part of a multipack and not for individual resale. If a single drive that you purchased as brand-new is listed as originally part of a multi-drive system, it is highly recommended that you contact your retailer and/or raise this with Seagate directly for further investigation.

‘Used Seagate EXOS HDDs Missold as ‘New – Other Drives Implicated
Now would be a very good time to check any hard drives you’ve purchased in the last 12 to 24 months! Recent reports from popular German news outlet Heise have raised increased reports of refurbished and modified SMART-reported drives being sold as brand new, leading to large concerns of widespread ex-cryptocurrency-burnt drives being sold through trusted business and domestic retailers. Although the scope of the issue seems to be largely focused on Seagate Exos data center-class drives, because of the wide-ranging drives that were used in Chia cryptocurrency mining several years ago, there is an increased likelihood that other large-capacity and high-durability drives should be considered, thanks to the relative ease of firmware modifications and larger quantities of HDDs being resold off the back of 5 year durabilities lines being crossed by the original coin miners!
Reports are now arriving that Seagate Ironwolf and Ironwolf Pro modified/mis-sold HDDs are now also affected. The extent to this is still too early to confirm, but the latest reports from Heise indicate that 8TB and 16TB HDDs have been highlighted.
Further reports from ComputerBase via a community member fanatiXalpha provided further evidence and indications of this via the images from the original article here:
REAL HDD
FAKE HDD
In this video I discuss multiple ways to initially identify issues with a ‘new’ Seagate Ironwolf HDD that do not involve connecting the HDD to a system. Later in this article cover several more methods that require connecting the drive to a NAS or general client system.
Check Your HDDs – Reports indicate used Seagate Exos hard drives are being sold as new, particularly 12TB-18TB models.
Firmware Manipulation – SMART data shows zero usage, but deeper FARM tests reveal 15,000-50,000 hours of prior use.
Widespread Issue – Over 200 reports from buyers in Germany, Japan, Australia, and other regions, spanning multiple retailers.
Crypto Mining Connection – Many affected drives likely came from Chia cryptocurrency farms (2018-2022) and re-entered the market fraudulently.
Tampering in Supply Chain – Drives may have been repackaged and resold by wholesalers and distributors, bypassing Seagate’s official channels.
Retailers & Seagate Respond – Some retailers are issuing refunds/exchanges. Seagate denies involvement and is investigating the supply chain breach.
Verify Your Drives – Use SMART, FARM, Seatools, and warranty checkers to confirm if your drive is genuine. Report suspicious drives to Seagate and your retailer.
What has been reported on the Seagate EXOS HDD Misselling
Earlier in the year, Heise reported that they had received dozens of reports from users who had purchased brand-new, enterprise-class Seagate Exos hard drives, only to find that when receiving the drives, they had scuffs and marks on them that suggested they were used—and used en masse. Further investigation of the hard drives using popular firmware tools initially showed that the drives’ SMART data was indicating little to no power-on usage. However, deeper investigation with deeper drive tools went on to reveal that the firmware had been manually adjusted to hide the tens of thousands of hours that these drives had already accrued in use.
Usage on drives has varied from between 15,000 hours and 50,000 hours, well over five years of deployment and well outside the warranty and workload rating on these drives in most cases. What is interesting though, is that retailers that have been impacted by this, and in fact a wide-ranging number of German retailers, have been highlighted as sources of these drives. However, reported issues span outside of Germany and include claims from purchases made in Japan, Australia, and other parts of Europe.
Fingers are initially being pointed at wholesalers, large-scale resellers, and distributors who supply the traditional retail and e-commerce websites that most users would be eligible to purchase from. Depending on the retailer, and several have already been highlighted in the now over 200 reports submitted to Heise, the returns and RMA process does differ from site to site, but this does appear to be a growing issue that most users will not even realize they have been hit by unless they take the time to investigate the usage data on their drives.
Primarily, Chia crypto farming has been highlighted as the origin of most of these drives, with huge quantities of large-capacity data center drives being purchased in 2018 to 2022, when this emerging and less GPU-centric form of cryptocurrency was being mined. Brands such as Seagate, WD, and Toshiba saw extraordinarily high sales numbers during this period for these drives, and equally, domestic users ended up being negatively impacted by supply shortages and price hikes. It seems that a lot of these drives that have either been abandoned from previously pursued cryptocurrency setups or just simply swapped out for ongoing farming have now made their way back into the supply chain under the guise of being regular, new, out-of-the-box drives!
The distribution channels, wholesalers, and affected e-commerce websites in order to ascertain how these drives have entered the supply chain and to what extent it has happened. They issued the following statement:
“We are taking this matter very seriously and are conducting a thorough investigation. As explained in the previous statement, Seagate did not sell or distribute these drives to retailers. We cannot provide details of the ongoing investigation, but we suspect that these drives are new products that Seagate sold to customers and were later resold by them on the used market. In this case, we believe that the drives were remarketed somewhere in the used market supply chain and resold as new. We recommend that retailers only purchase drives from certified Seagate distribution partners, as purchasing from certified Seagate distribution partners is the best way to ensure the authenticity of Seagate products for retailers and their customers.
Seagate has processes in place to investigate these types of cases, with teams working proactively with our vendors to take action where necessary. Our security team also regularly works with local authorities to take necessary action. Many investigations are initiated based on anonymous tips and reports from partners and customers. These measures are designed to protect Seagate partners and end customers in an increasingly global marketplace.
We encourage anyone who suspects they have received a used drive marketed as new to help with the investigation by reporting the incident to us directly at [email protected] . In addition, customers who have doubts about whether the products they purchased match the claims of the sellers can access our warranty checker tool . Suspicious drives and/or sellers can also be reported anonymously through our Ethics Hotline .
Currently, the bulk of aggregate reporting of this is going through the Heise website, and a lot of the submissions have been done via their anonymous reporting link, so exact model IDs are hard to track down right now. However, the bulk of the reported mis-sold drives appear to be Seagate Exos drives ranging from 12TB to 18TB. As mentioned earlier, however, the original reporting suggests that other drives have been highlighted by users. Realistically, it’s pretty unlikely that only Exos drives are going to be impacted as such. A wide-ranging procurement took place during the peak of Chia cryptocurrency farming, and pretty much any moderately durable, high-capacity hard drive was changing hands quickly at that time. This all does seemingly indicate right now that a lot of these drives are being offloaded with their firmware modified by one or a handful of bad actors, who likely are sitting on high quantities of the same hard drives. However, it would not surprise me whatsoever if over the coming months and years, we see spikes on affected drives outside of the Seagate Exos data center series.
How Can I Check If My Drives Were Mis-Sold as New?
There are multiple ways to check whether the hard drive inside your system, which you purchased as brand new, is actually new. However, the suitability of each tool will depend heavily on the system type and operating system your drive is running on. Seagate’s Seatools application allows you to check and validate multiple data points on your hard drives. However, it is only available as a Windows or Linux client, as well as a portable version. That means Mac users, or those less comfortable with command-line tools, may find it difficult to use—not to mention users who have multiple drives deployed in systems without a suitable GUI or command-line interface for validity checks. Below, I’ve broken down recommended tools and commands that you can use to verify your drives, their power-on hours, and other critical details.
How NAS users can Check and Verify the usage of the HDDs:
NAS users who suspect their drives may have been mis-sold as new can verify their SMART data and power-on hours using various tools. Most NAS operating systems, including Synology DSM, QNAP QTS, TrueNAS, and UnRAID, have built-in SMART monitoring tools within their storage manager or disk health sections. These tools provide essential SMART attributes, including Power-On Hours (POH), Reallocated Sectors, and Drive Temperature. However, in some cases, the SMART data may have been manipulated to show zero usage, making further verification necessary.
For deeper analysis, users can SSH into their NAS and install smartmontools, a command-line utility that provides detailed drive health reports. Running the command:
smartctl -a /dev/sdX
(where X is the drive identifier) will display all SMART attributes, including power-on hours. However, if the SMART data has been reset or manipulated, users can check the FARM (Field-Accessible Reliability Metrics) values for a more accurate picture of a drive’s actual usage history. To retrieve FARM values, NAS users can use:
smartctl -l farm /dev/sdX
This will reveal true power-on hours, drive usage patterns, and whether a drive has been extensively used before being reintroduced into the supply chain.
For those using QNAP or Synology NAS devices without direct access to smartmontools, Seagate’s Seatools (Windows/Linux) can be used by connecting the drives externally via a USB or SATA dock. Additionally, Seagate’s warranty checker tool allows users to verify if their drive was originally part of a multi-drive batch—a red flag that it may have been previously used in a server or data center environment.
How NAS Users Can Check SMART Data and Power-On Hours Over SSH (Including FARM Values for Verification & Integration with Smartmontools)
NAS users with SSH access can perform a deeper, more accurate verification of their hard drives’ SMART data and power-on hours to detect possible tampering. While many NAS systems, such as Synology DSM, QNAP QTS, TrueNAS, and UnRAID, provide built-in SMART monitoring via their web interface, these tools often rely on basic SMART queries, which may not reveal manipulated or reset power-on hours. By accessing the NAS via SSH, users can run Smartmontools directly, allowing them to extract FARM (Field-Accessible Reliability Metrics) values, which are not included in standard SMART logs.
To begin, users should SSH into their NAS and install Smartmontools if it is not already available. On Debian-based NAS systems (such as OpenMediaVault, TrueNAS SCALE, and some QNAP models running Debian Linux), install Smartmontools with:
sudo apt update && sudo apt install smartmontools
On Red Hat-based systems, use:
sudo yum install smartmontools
For NAS systems that do not allow package installations, users can still manually compile Smartmontools or install a Docker container that includes the tool.
Once Smartmontools is installed, running the command:
smartctl -a /dev/sdX
(replacing X with the correct drive identifier) will display SMART attributes, including Power-On Hours (POH). However, since bad actors can manipulate SMART data to show zero hours, users should perform an additional FARM query with:
smartctl -l farm /dev/sdX
Unlike SMART power-on hours, which can be reset, FARM values track long-term reliability metrics stored at a deeper firmware level, making them much harder to falsify. If there is a discrepancy between SMART-reported power-on hours and FARM-reported power-on hours, it strongly suggests that the drive has been used before but was manipulated to appear new.
Integrating Smartmontools into a NAS for Automated Checks
To automate drive health monitoring, NAS users can schedule periodic SMART and FARM scans using cron jobs or integrate them with the NAS system’s notification service.
Create a SMART Monitoring Script Users can create a simple script to check SMART and FARM values for all installed drives and log the results.
#!/bin/bash
LOGFILE=”/var/log/smart_check.log”
echo “SMART Check – $(date)” >> $LOGFILE
for DRIVE in /dev/sd[a-z]; do
echo “Checking $DRIVE…” >> $LOGFILE
smartctl -a $DRIVE >> $LOGFILE
smartctl -l farm $DRIVE >> $LOGFILE
done
Save this script as smart_check.sh and make it executable:
chmod +x smart_check.sh
2. Schedule Automated Checks with Cron Users can schedule the script to run daily or weekly using cron. Open the cron editor:
crontab -e
Add a line to run the script every day at 2 AM:
0 2 * * * /path/to/smart_check.sh
Set Up Email Alerts for Failures To receive email alerts if issues are detected, modify the script to check for critical SMART attributes and send an email if problems are found:
smartctl -a $DRIVE | tee -a $LOGFILE | grep -i “Pre-fail\|Reallocated_Sector_Ct\|Power_On_Hours”
smartctl -l farm $DRIVE >> $LOGFILE
done
# Email log if issues detected
if grep -q “Pre-fail\|Reallocated_Sector_Ct” $LOGFILE; then
mail -s “SMART Error Detected on NAS” $EMAIL < $LOGFILE
fi
By leveraging SSH, Smartmontools, and automated monitoring, NAS users can go beyond surface-level diagnostics and ensure they are not just scraping the same potentially manipulated data, but actually verifying their drives’ true usage history.

smartctl -l farm /dev/diskX
This will reveal the true runtime history of the drive, even if the SMART data was manipulated to show zero or low usage.
For users who prefer a graphical interface, DriveDx is a third-party macOS tool that provides SMART data, health status, and power-on hours. However, DriveDx does not display FARM values, so Smartmontools remains the best option for deeper diagnostics.
Since Seagate’s Seatools is not available for macOS, users can create a bootable USB drive with a Linux live environment (such as Ubuntu), run Seatools from there, and check the drive’s SMART health and warranty status. Additionally, Mac users can enter their drive’s serial number into Seagate’s online warranty checker to confirm if the drive was originally part of a batch sale, which may indicate prior enterprise use.

Seagate has not had any involvement in their reintroduction into the supply chain. Somewhere along the line, these used drives were inserted into the system, and that is what Seagate is currently investigating. The retail outlet where an affected user purchased the drive has more than likely been completely unaware that they have been selling used drives as new. In most cases, these drives would have arrived in sealed retail packaging, and the retailers would have been reluctant to open up supposedly new products for testing, as doing so would immediately devalue the product in the eyes of their consumer and business buyer base.
Therefore, it is going to take time for Seagate to find the smoking gun and pinpoint which wholesaler, reseller, or distributor allowed these used drives to re-enter the supply chain.
Is Selling Used/Refurbished Hard Drives Illegal?
The sale of used, data center-grade, refurbished, or officially recertified drives is completely legal. Although Seagate, WD, and Toshiba would probably prefer to see the used hard drive market disappear, selling used drives is not illegal.
Many online retailers, including Amazon and Newegg, actively sell recertified and renewed drives—just as easily as brand-new ones.
The problem here is that these were used drives that were fraudulently mis-sold as brand new—and that IS illegal. In short, this is fraud, and the people selling these drives could be pursued for damages if customers lose data due to these drives failing far sooner than expected. That’s why any drive that isn’t new is required to be labeled as recertified, refurbished, or renewed. This ensures clarity for the buyer when making a purchasing decision.
That said, some sellers intentionally make it hard to determine if a drive is refurbished. For example, a Seagate IronWolf 12TB hard drive sold on Amazon’s “previously owned” listings might clearly state that it’s used—but it won’t mention that it was originally manufactured in 2017, meaning it could be 8 years old and already have tens of thousands of hours of prior use. It wouldn’t be so bad if the manufacturing date was displayed at the top of the listing, but instead, it’s buried deep in the product details. Bottom line: Selling used drives is not illegal. Selling used drives under the guise of being brand new is fraud—and highly illegal.
Is This Seagate’s Fault?
In all honesty, one could argue that Seagate is responsible for selling large volumes of high-capacity, data center-class hard drives to the original cryptocurrency farmers. However, this would be no different than selling the drives to any regular SMB, just a question of large-scale volume. Seagate is not responsible or in any way officially authorizing the reselling of its hard drives under the classification of new storage media. Additionally, the official partners that Seagate chooses to sell its goods through have almost certainly sold these drives with as much authentication between them and the distributors/resellers as possible. It could be argued that Seagate should personally step in at the supply chain level further down the chain to periodically check the health and condition of drives—much like a hard drive secret shopper—but that’s really about it. Right now, as long as Seagate commits to investigating how this occurred and acts upon what they find to ensure that mis-sold drives don’t enter the supply chain again, that’s about as far as I think this can go in terms of blaming Seagate. Realistically, we can’t lose sight of the fact that it is the fault of the bad actors who modified these hard drives in an effort to recover the original money spent on them before Chia farming collapsed. Wherever the entry point was that allowed these drives to re-enter the supply chain, that is what needs to be identified and stopped.
What Should I Do if I Believe my HDD was Missold?
If you believe that the hard drive in your NAS, server, or storage system was mis-sold to you as a brand-new drive when in fact it was heavily used, you need to contact your point of sale immediately. Tools such as Seagate’s own warranty checkerallow you to enter the serial number of your hard drive into their database checker. Regardless of whether your hard drive is still under warranty, it will still highlight whether this is an official drive or not. Additionally, if you purchased a single drive that was sold as new, but upon entering the details into the warranty checker on Seagate’s website shows that this drive was part of a larger batch, this would imply that the drive you purchased was originally included in a larger server system previously—not unlike how a food or drink product is labeled as part of a multipack and not for individual resale. If a single drive that you purchased as brand-new is listed as originally part of a multi-drive system, it is highly recommended that you contact your retailer and/or raise this with Seagate directly for further investigation.
