NT 4.0 Workstation - Missing SCSI disk

We recently retired an external box of 4 scsi disks from our unix server and want to use it on an NT 4.0 (SP.6) workstation. When the machine boots up it reports 6 scsi devices (1 internal disk, plus 4 external disks and a CD ) but NT only sees 4 disks plus the CD.

Is there some restriction on the number of scsi devices or can anyone suggest some other reason for the missing disk?
 
The only limit to the number of SCSI drives is that you can have 7 devices per bus. You are well within that range. I would suggest that you check the cables as well as the SCSI IDs. If it doens't show up under NT, it most likely is not formatted. If it doesn't show up in the Disk Administrator, then I don't know what the problem is.
 
paulip88, that's not entirely correct what you said about the 7 device limitation. 8-bit SCSI(a.k.a. Narrow SCSI) IS limited to 7 devices+the SCSI controller. 16-bit SCSI(a.k.a. Wide SCSI) is only limited to 15 devices+the SCSI controller.

Sam443, what did you mean by "NT only sees 4 disks?" If there are partitions on those SCSI disks with file systems that NT 4.0 doesn't support, you won't see them in the Windows Explorer or the Command Prompt. You should still see all of the disks in Disk Administrator. If not, tell us the detail of your hardware, like SCSI controller and SCSI devices, and maybe we can tell you what's wrong.
