I'm pretty sure that SCSI drives, or at least more modern ones, do.  The
ones I've used have a list of bad blocks stored internally and will
relocate blocks automatically.  The drives allowed you to reset this
list by running a low level format from the scsi controller.  The drives
would then clear the bad blocks list and recheck disk blocks again.
