Clean the head with the cleaning cartridge.
■
Replace the data cartridge with a new cartridge.
■
Make sure that you are using the correct data
cartridge.
→
• Make sure that you are using a correct
drive and cartridge combination, for
example that you are not using a DDS3
cartridge in a DDS2 drive.
• Make sure that you are using a type of
cartridge for which operation is guaranteed
(EF-type cartridge, etc.).
• Make sure that you are not using a
cartridge that has reached the end of its
operational life.
• Make sure that you are not using a
cartridge on which there are errors.
■
There may be a problem at a one or more of the
following connections: SCSI cable, connector,
the terminator, etc.
→
Check the connections.
■
If the drive was moved to an environment with
different temperature and/or humidity, the drive
may not have fully adapted to its new environ-
ment. Allow the drive time to adapt to the new
environment before using it.
■
If the backup process is initiated immediately
after system startup in an environment that is
not air-conditioned, the drive may not have fully
adapted to the environment. Modify the
operating procedures so that the drive is allowed
to time to adapt before beginning the backup
process. (This problem frequently occurs when
the system starts up in the middle of the night
and begins the backup process.)
■
Make sure that the backup software is installed
correctly.
■
Make sure that there is no other device on the
SCSI bus with the same SCSI ID.
■
Make sure that there are no software conflicts.
→
If there are incompatible device drivers
installed on the system, it may be necessary to
remove some of the drivers. Refer to the
appropriate software documentation for details.
