Power-on sequence. For the external tape drive, make sure that you
power on the tape drive before you power on the computer.
When you start your computer, the SCSI adapter card searches for
SCSI devices attached to the computer. If your tape drive is not
powered on at this point, the SCSI adapter card cannot detect it.
!
Software installation. Make sure that your backup software is installed
correctly. Refer to the documentation that came with your software for
installation and troubleshooting instructions. Pay special attention to
steps describing configuring the software for use with the tape drive.
After checking all the items listed, reset the SCSI bus by turning off the
tape drive and the computer. Then, power on the tape drive first,
followed by the computer.

Problems with tape drive operation

Most problems with tape drive operation occur with improper cartridge
use. If you have been successfully operating your backup software and
tape drive in the past, but are now experiencing problems reading and
writing data, check the following:
!
Write-protect switch. If you are writing data, make sure that the
data cartridge is write enabled.
!
Data cartridge brand. Check the brand of data cartridge you are
using. For best results, use EXATAPE™ data cartridges. See page 43
for more information.
Owner's Manual
To prevent possible loss of data, make sure that any other
devices on the SCSI bus are inactive and have completed all
requested operations before powering off the tape drive or
resetting the bus.
