It's the third USB enclosure that fails on me in one year! That's about par for the course, I think. I simply don't trust USB storage enclosures at all... > The other disk failed again.

Sense: Unrecovered read error - auto reallocate failed Basically, this is saying the sector on the disk is bad, and there is no spare sectors on the disk for recovery of that sector. i.e the sector is now permanently dead. The drive is essentially unusable at this point - it will only continue to get worse and lose more data. AFAICT, the only way you'll get anything off this drive is via ddrescue to image it and then perform data recovery on the decayed corpse it extracts....
