In either case, the SCSI tape driveis controlled by a SCSI host adapter installed in the com-puter, which may also control other SCSI devicesconnected to one or more SCSI cables. SCSI devicesoften require device drivers for the particular operatingsystem being used by the computer system.Tape drive problems often result from a defective tapedrive, a defective tape cartridge, or software.
