SCSI recommends rewrite -- how?

Hi,

I've been getting the following error message turn up in my syslogs
at irregular intervals (a couple a week):

Jan  3 06:29:37 vlad kernel: Info fld=0x49c21c, Current sd08:18: sense key Recovered Error
Jan  3 06:29:37 vlad kernel: Additional sense indicates Recovered data without ecc - recommend rewrite

The Info fld=... value changes.

Two questions:

- If I read Documentation/devices.txt correctly, this would appear to be the second SCSI disk, second [primary] partition. This is a problem, since that partition doesn't exist -- there's a single primary partition on that drive, containing 4 logical partitions.

- Secondly, how can I identify the relevant bit of the disk that wants rewriting? Is the fld=0x... the offset on the drive, or the partition, or what?

Thanks,
Hugo.
