Writing zeros is certainly what I'd do in this situation - I've done it
for several drives in the past where they've had offline uncorrectable
sectors flagged.

I just tried to write zeros, it didn't help: the disk doesn't reallocate the bad sector :(

Something isn't right. How did you write zeros?

I went through the archives and wasn't able to find the full smartctl -x results for this drive, can you post them?

Does anyone know for sure if the ATA Secure Erase command verifies its writes? i.e. does it even have a way of knowing if there are bad sectors on a write and remove them from use? Or is the write-read verification always occurring on hard drives?
