A SCSI tape drive can be an internal device installed in one of the externally accessi-
ble drive bays or an external device that attaches to a SCSI host adapter connector on
the back panel of the computer. The SCSI tape drive is controlled by a SCSI host
adapter card installed in the computer, which may also control other SCSI devices
connected to one or more SCSI cables. SCSI devices often require device drivers for
the particular operating system being used by the computer system.
Tape drive problems often result from a defective tape drive, a defective tape car-
tridge, or software. Follow these steps to troubleshoot a SCSI tape drive:
