❑
Make sure that the device driver is installed
correctly.
→
In some cases, the device driver may be
installed automatically. In other cases, it may
be necessary to install the device driver
manually. In still other cases, the device
driver may be incorporated into the product.
Refer to the User’s Guide for details.
❑
Make sure that the device driver started
correctly.
❑
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.

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 environment. 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.)
