SCSI tape drive

SuSE 10.0 I've added an adaptec SCSI card and Wangdat 3400 tapedrive from an old system into my SuSE server. As yet, the tape drive does not appear in YaST and I don't seem to be able to find it in /dev/scsi (just tells me about directories . and ..) Running /etc/rc.d/boot.scsidev doesn't find it either. Any thoughts, please? When I've found it, I guess I'll have to mount it (fstab) before I can use it for backups. TIA John
