Are you sure its SCSI and not mini-IDE? As the A1200 only has a single 44-pin mini-IDE connector on the motherboard. The only way it could be SCSI is if you have a PCMCIA SCSI controller or a Accelerator board based SCSI controller. Either way, make sure the drives paramaters are correct and make sure you save any changes you make. Once you have done that, reboot and you should see something like "DH0:NDOS" on the Worknbench. If that appears try and do a format.
