Not likely, though just looking at *how* it fails, if the data'd not
already been backed up, I'd hold at least a little hope that it's not
really a problem with the on-disk data, aside from what's been
corrupted since the problems started, but rather just the controller
and firmware. If I had a spare drive from the same batch, I'd swap in
the not-dying controller card and see if that got me anywhere. Since
the drive's already backed up, though... that one's a new paperweight
for the desk, and if the data's anything sensitive, physical
destruction of the drive's the way I'd go to 'secure' it before it
goes out with the trash.

because defectice partitions don't give you no sense errors nor do they give

you zero capacity errors. Read his dmesg.



Â*If the firmware/logic board is bad, you might be able to replace it with one from the same model. Â*I've heard of some success from a coworker who took the logic board from a known good drive and put it on a HDD with good internals but a bad logic board, and it worked. Â*That's if you need the data, that is.
