Well, that _could_ be a sign of a failing drive, but my offhand
impression is that's really thin in the context of the BIOS raising an
alarm during POST.  It doesn't seem to match.

If during diagnosis you isolate peoblem cause to a specific physical
drive device, don't hasten to throw it away without some further steps.
Specifically, each manufacturer (Samsung, Western Digital, Seagate,
etc.) offers for download diagnostic and repair software that in many
cases can massage an old drive into like-new condition.  Look around and
find (and use) the one for your device.  Example:
