[rescue] Rescue a disk?

[Scott Newell]

I've noticed that one of my larger scsi drives is giving file system errors
at bootup.  Are there any decent tools available for *bsd to find and mark
the bad sectors?  There's no critical data on the drive, so a total
reformat isn't out of the question.  (I'm not very experienced with SCSI
drives, so I really don't how to force the drive to remap sectors.)
