Also, the drive is extremely slow now, about 1MB/s drive transfer rate as reported by hdparm -T.

That should read "hdparm -t", not "-T", right?

erk, sorry, yes.

And the slowness is most likely due to the error recovery (retries) in the drive and/or driver, which cause the overall throughput to plummet for the measurement interval.

ah. There are no reported errors though. So presumably drive retries that end up being successful.

If that is so then this suggests the drive has a far more serious problem than just a single bad block, right?

Cheers
