  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.


Based on all of the above, I now suspect a hardware problem with
/dev/sdb (as you suspected), which was formerly /dev/sda.
There were two errors with the drive currently attached to /dev/sda, but if they
don't come back, I won't worry.

Do you concur?

Thanks,
