Missing or Damaged Parts

If any of the contents included with your DDS-4 or DAT 72 drive are missing or damaged, contact

your place of purchase immediately.

SCSI ID Problems

Each SCSI device on the same SCSI bus must have a unique SCSI ID. The default SCSI ID for the

DDS-4 and DAT 72 drives is 6. You should leave this default SCSI ID unchanged unless another

device on the SCSI bus is already using this ID.

If the default SCSI ID is already in use, you can change the default SCSI ID on the drive using the

SCSI ID Selector switch on the back of the external SCSI drives. After you set the SCSI ID, record

your setting.
