Dan, I think you're thinking of an IDE drive, not a SCSI drive. Part of the SCSI spec requires the drive at least acknowledge the FORMAT UNIT command, and the vast majority of SCSI drives not only acknowledge it..but do it. The only way you can mark bad blocks on a SCSI drive is to add them to the defect list via the FORMAT UNIT command. The on-unit ROM handles the details of how to format the drive and the remapping of the sectors, the only option to the user is the interleave value. Don
