It depends on your controller how you do a scsi verify (unless someone has
a linux tool for it ?). All scsi verify does is read each block and if its bad
or marginal (remember the drive knows more than the end OS can see) it will
remap it, and if possible copy the data to the remapped block. At that
point e2fsck should be happy.

SCSI verify is basically asking the disk to clean itself. When you get
disk errors making a backup is very smart anyway.
