You don't need any special Seagate tools if it has SMART. Ubuntu live CD and
"disk utility" runs the palimpsest program mentioned above.

Modern drives will flag the bad blocks. If it is just a few, you can fix it
by deleting or overwriting the files that are getting errors on reading.
e.g. from backup.
The drive will attempt to write over the block and verify it. If the verify
fails, it will automatically mark the block as bad, and use a spare. (Do I
understand correctly folks?)

Yours is a rather old SCSI disk, but I'd guess it does the same.
