Also, the drive is extremely slow now, about 1MB/s drive transfer
rate as reported by hdparm -T.
Sounds like it dropped to PIO - that may be a bug triggered by the drive
failing.
That should read "hdparm -t", not "-T", right?
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.
Cheers
