Maybe I was just lucky, but I had an uncorrectable sector error at one point,
and ran a dd write on the drive, and SMART reported the sectors were
corrected. It wouldn't do it with a read, but a full write worked. The drive
worked for quite some time after that. I might still have it, but I can't
remember which drive that was (I've had a lot).
