It's a different sector number every time, and this is the third drive
that I have tried in that enclosure (the first two being rather recent
models made by Seagate, the one that you have seen the log from an
older IBM DTTA from 1999).

I am pretty sure it's not the drive (I have tried three), but can the
USB adapter in the system be a problem as well?
