Hardware-encrypted SSDs sold under the TCG Opal2 standard cannot be assumed safe just because they ship with encryption features turned on. Researchers tested 38 drives from multiple vendors and found broken or weak behavior, including predictable random numbers, flawed PSID reset tokens, and, on some Lenovo OEM drives, a tweak value reused across the whole disk. One drive firmware issue was fixed by Micron, but many other reports were already known, unpatched, unsupported, or ignored.
