This will allow you to mark a sector to be bad in the FAT. And also if you used Adaptec 4070 controller, the bad sectors are map out by the card when it format the disk ( that's what I remember but not 100% certain, but do seems to recall some SCSI card map out the bad sectors so that the host sees the hard drive as no bad sectors).
