This is normal, since usually the SCSI controller has ID7 already reserved
for itself, thus your SCSI bus is messed up if you have 2 SCSI IDs.

If you have only SCSI disk on your system, the boot partition can be either
ID 0 or ID 1, but with some controller BIOS it's safer to be at ID 1.

Max SCSI ID # is 7 (range 0-7) - AFAIK

If you set your DAT to ID 1-6 and the SeaGate to ID 0, everything should
work fine!
