General Procedure

If a problem occurs, the first step is to try to establish whether the problem
lies with the cartridge, the drive, the host computer and connections, or the
way the system is being operated.

Has the system just been installed?

There could be an installation problem:

1.

Check through the information in the relevant installation chapter of this
guide.

2.

Check the power connectors.

3.

Is the SCSI ID correctly set? Is there a SCSI system conflict? Has the
SCSI bus been correctly terminated? See also

SCSI configuration guide

” on page 49.

4.

Check the environmental conditions against the specified limits.

5.

Are appropriate drivers and application software installed on the host?

Are you using new cartridges or a different brand of cartridge? Have
you been using the particular cartridge for a very long time?

The problem could lie with the cartridge:

1.

Check through “

Use the correct media

” on page 39.

2.

Check that you are using a DDS-labeled cartridge—not a DAT cartridge.
