Problems with cartridges
If you experience any problems using HP branded cartridges, check:
• The cartridge case is intact and that it contains no splits, cracks or damage.
• The cartridge has been stored at the correct temperature and humidity. This prevents condensation.
See the insert included with the tape cartridge for storage conditions.
• The write-protect switch is fully operational. It should move from side to side with a positive click.

NOTE:
When using the NT backup application with HP StorageWorks DAT 160 or DAT 320 tape drives,
the user must choose 4 mm even when using 8 mm tape cartridges.
The cartridge is jammed
If the cartridge is jammed or the backup application is unable to eject it, you can force eject the
cartridge. Once the cartridge is successfully ejected, it is good practice to upgrade the firmware. If
the failure occurs regularly, contact customer service at http://www.hp.com/support.
1. Either press and hold the Eject button on the front of the tape drive for at least 15 seconds. Or
press the Eject button three times within 5 minutes.
2. Wait for the cartridge to be ejected. The drive waits until 35 seconds have passed from the time
of the first press, to give the normal eject procedure a chance to proceed. After this period, it
immediately releases the tape and ejects the cartridge, regardless of what operation it was
performing. It is important that you allow sufficient time for the drive to complete this process. If
you interrupt it, you may damage the media or the tape drive. The drive is then reset as though
you had turned the power off and then on again.
You may lose data if you force eject a cartridge. The tape may also become unreadable because
an EOD (End of Data) mark may not be properly written.
3. If the cartridge is still jammed, the tape drive has failed. Contact customer service at http://
www.hp.com/support.
The drive will not accept the cartridge (or ejects it immediately)
The cartridge may have been damaged, for example dropped, or the drive may have a fault. If it is
a cleaning cartridge, it has probably expired and should be discarded immediately. For data
cartridges:
1. Check that the drive has power (the power cable is properly connected and the Tape LED is on).
