I have seen numerous cases where HDDs and SSDs suddenly become unallocated.
Here is one such thread:
https://forums.tomshardware.com/threads/hard-drive-issues.3680176/#post-22165140The common factor appears to be AMD Ryzen / Windows 10 platforms, and users often report these issues after a motherboard swap. Even after repairing the damage to sector 0, the same problem recurs randomly in subsequent boots.
I suspect that the problem may be related to AMD's SATA driver, but I'm not certain.
The damage to sector 0 often results in the data pattern in the attached screenshot. The partition table is also cleared.
In one case I saw a remnant of NTFS metadata (part of the $LogFile, IIRC).
Are people seeing this kind of damage in their shops?
