Some (PC) SCSI host adapters (controllers) use ID=0 for themselves.  So
you can't use that ID for a drive.

Most (workstation) SCSI host adapters use ID=7, so you don't use that ID
for a drive.

DEC had the habit of setting the controller ID to 6 in MicroVax/
VaxStation 3100 systems.  Draw your own conclusion.
