I think that not only is it a bad sector, it's a bad sector that your
SCSI drive has failed to remap to a good one. Have a look at the grown
defects list (scsiinfo -d /dev/sda | less) - if it's full, back up
your drive ASAP and get a new one.

How do you know if it's full if you don't know how big it can be - if
the number of entries is a suspicious number like (2^n)-1, it's
probably full.
