Démonter un HDD pour remplacer son PCB

1 avril 2022 à 22:43
Par : Mr Xhark

Un disque dur mécanique est composé d'une carte électronique (PCB) et d'une partie mécanique : plateaux, moteur, etc. Il peut arriver que la carte électronique tombe en rade. Soit à cause d'une surtension, soit à cause d'un composant électronique qui rend l'âme. Dans ce cas il est possible d'acheter cette carte pour l'intervertir avec celle d'origine défectueuse.

C'est que nous propose Stéphane dans cette vidéo de réparation, sans toutefois tenter de récupérer les données. Le but pour lui était de ne pas jeter le disque, il l'a donc formaté quand la partition était détectée en raw (c'est à dire sans qu'elle soit reconnue).

ℹ : on retrouve le même programmateur de puce TL866 que celui que je vous ai présenté dans le sauvetage d'un PC Portable DELL (écran noir).

Il y a de fortes chances que des outils comme TestDisk ou DiskGenius seraient parvenus à détecter les partitions en balayant les secteurs du disque, pour ensuite récupérer les données. Dommage de ne pas avoir poussé la réparation jusque là car la majorité du boulot était faite grâce au dump de la puce EEPROM.

Une compatibilité loin d'être évidente

Ce qu'il faut savoir c'est qu'il existe un grand nombre de firmwares, versions de PCB. Même quand vous tombez sur une carte qui vous semble très proche il y a très peu de chance que vous soyez sur une version totalement identique. Cela veut dire qu'il y a très peu de chance de récupérer les données en changeant la carte sans procéder au dump de la puce d'origine.

Démonstration en salle blanche

Dès qu'il faut aller plus loin en permuttant les plateaux il faut concentration de particule très faible (salle blanche), des outils et logiciels professionnels hors de prix et un savoir faire qui n'est pas à la portée du débutant.

Je vous conseille d'aller voir la chaine YouTube canadienne HDD Recovery Services dont voici une mise en bouche :

Il travaille également sur divers périphériques de stockages : cartes mémoire, SSD. Franchement intéressant.

Troubleshoot Where To Enable MSI Gaming Plus Max B450 Virtualization

31 juillet 2021 à 21:57

Recently I upgraded my motherboard (to MSI Gaming Plus Max b450) with a newer chipset to have better support my previous upgraded Ryzen 3700X CPU. Obviously, when you ‘upgrade’ a motherboard, it’s rather a full new build again just with existing parts and that the only scenario you are expecting is everything turns back on and hopes it works again. Sadly this isn’t the case, and it is by far the most frustrating build I’ve done!

I hope this tip can save you endless re-tries or hours of reading and watching videos online or even making the wrong decision to RMA your motherboard when things don’t work out.

So what doesn’t work out?

No virtualization.

Unlike what this motherboard’s name suggests, I don’t plan to use it for gaming. I need it to speed up my daily work, and my work involves running docker containers and running virtualized OS. And by default, the setting for AMD’s Ryzen virtualization technology (SVM mode) is disabled.

Other settings > missing CPU Features

So let’s enable it in the BIOS. But you will soon realize if you follow most other guide out there by going to Advanced > OC > Other Settings > (looking for CPU features). The setting is missing from my motherboard. What?!

Long story short, after more digging and countless BIOS version flash, the answer lies in the above menu. The SVM mode setting has been moved under OC > Overclocking > Advanced CPU Configurations.

This is where you can change the SVM Mode from Disabled to Enabled.

I hope this solves your issue of enabling virtualization with the MSI B450 Gaming Plus Max motherboard. Unfortunately, there are more headaches for me with this motherboard that I have yet to figure out. The board would sometimes think CPU is not detected. As a result, nothing boots up.

Three Ways to Upgrade a Gigabyte Motherboard BIOS

1 mai 2021 à 01:56

If you’ve followed my previous few posts on CPU upgrades, you’ve learned that updating your motherboard’s BIOS is critical to having a successful upgrade. Regardless of your reason for BIOS updates, here are few different ways I want to share with you when it comes to upgrading a Gigabyte motherboard’s BIOS.

Method One: Install Gigabyte App Center and @BIOS app

The most straightforward method that allows you to update BIOS all within Windows and I recommend most folks use this method. All you need to do is download the utility and run the installer. Follow the onboard instruction to update the BIOS. In order to install @BIOS you need to first have the Gigabyte’s App Center installed.

Method Two: BIOS Q-Flash

The traditional method is to go to the BIOS screen and flash the BIOS version from there. For Gigabyte, the flash tool is called Q-Flash. You download the binary and put it on your USB, boot into the BIOS screen and find the version from USB to proceed with the upgrade.

Method Three: Q-Flash via Dedicated USB Plug Directly

Almost all modern Gigabyte supports this; you need to read and check the instruction menu for your specific motherboard. It would help if you looked for a USB that’s dedicated to Q-FLASH to update BIOS. The most recent one, it’s a USB slot with white strips on the tongue.

Unplug everything else and power on the motherboard, and it will proceed with the BIOS upgrade. For this method to work properly, you want to have a USB drive with LED read/write an indicator to tell when the update is finished. This is a good method to proceed if you have lots of hardware need to perform the same update. It requires no supervision, just the right binary for the bios in the root drive of the USB, and it will proceed with the upgrade.

Troubleshoot CPU Upgrade – Ryzen Zen/Zen+ to Zen 2 (Ryzen 3000 series)

1 mai 2021 à 00:23

Just this week, I came across an article from Wired titled “Don’t Underestimate the Challenge of Building a PC,” right then, it resonates with me. I totally feel both the reward and frustration when you successfully finish building your very own PC.

Today, we will walk through one of my frustration when it comes to upgrading my own AMD Ryzen build from a Ryzen 3 1200 CPU (or any Ryzen 1000 series) to Ryzen 7 3700x Zen 2 (3000 series, or 3rd Gen Ryzen) CPU while keeping everything else the same. Some background sets the stage so you can reference if you have trouble upgrading the CPU when it comes with yours. I’m running:

  • Motherboard: Gigabyte GA-AB350M D3H
  • CPU: Ryzen 3 1200 (was) => Ryzen 7 3700x (new)
  • 4 slots of DDR4-2400 RAM each with 8GB from Samsung (this became important information later on)
  • Graphics Card: Radeon RX 560 Series
  • SSD: 250GB HP M.2
before the upgrade

Like I mentioned in a previous post on what you need to know when it comes to upgrading your CPU.

The key information here is the B350 chipset. If your motherboard is from another manufacturer (i.e. MSI), you too can follow this guide; it should be very similar, but some specific steps might be different. This chipset, according to AMD, should support up to the Zen2 series of CPUs which is the lineup named with the Ryzen 3000 series. You also want to check with your motherboard to ensure it supports the CPU you wish to upgrade. It is also worth mention that reinstalling Windows is NOT required for this upgrade to work.

Troubleshoot Why CPU Upgrade Didn’t Work

After I followed all the steps were in the previous post. I started up the desktop, and nothing loads. I get a blank screen, and around 10 seconds, the PC would power cycle and continue reboot itself. And the motherboard I have does not have onboard diagnoses LED, so you can’t tell which part of the motherboard panic and didn’t even load the BIOS screen.

What ends up helping me solve the issue is the user manual and Gigabyte Support website. I missed two key steps when it comes to preparing the upgrade. First, I had no recollection of when and how I upgraded the existing motherboard’s BIOS. All I know it’s not running the original, and it’s the second most up-to-date BIOS version, which should support the new CPU that I’m upgrading to. This post a problem as, according to the Gigabyte GA-AB350M-D3H manual, you have to upgrade the BIOS in sequential steps! While you can jump and upgrade the BIOS to the latest, it often doesn’t contain the proper function if you skipped some required version.

The other missteps I made was if you want to use all four RAM slots on the motherboard with the new CPU you need to run the “EC FW update Tool” and this also requires the chipset to be upgraded. Otherwise, you cannot run even if you upgraded the BIOS with the proper step upgrade.

Note:
1. If you are using Q-Flash Utility to update BIOS, make sure you have updated BIOS to F31 before F40.
2. Before update BIOS to F40, you have to install EC FW Update Tool (B19.0517.1 or later version) to avoid 4DIMM DDR compatibility on 3rd Gen AMD Ryzen™ CPU.
3. Due to BIOS ROM size limited, NO Bristol Ridge (AMD 7th Gen A-series/ Athlon™ X4 series) APU support.

As a result, the EC FW update Tool upgrade triggered the backup BIOS to load and my BIOS was completely reset to the original F version.

So this actually made the upgrade easier as the first required upgrade is F31, the next would be F40 and lastly, the latest upgrade is F51c. That is 3 BIOS upgrades if you wish to upgrade to the latest.

Once you are on the latest then try to swap the new CPU in again. This time it worked after many failed attempts.

I was about to open a return order for the new CPU and thought to give this one more try and this time it paid off. This speaks to how important to read every single instruction and have it well prepared if you want to do a heart surgery for your desktop. It worked for me hopefully it will work for you! I’m counting on this new build to last for another 10 year down the road.
