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).
2. Check that you are using the correct media for the tape drive, see
“Use the correct media” on page 49.
3. Make sure that you have loaded the cartridge with the correct orientation (see
“Loading and unloading” on page 47).
4. Check for damage to your media and discard it if it is damaged.
5. Use a new or known-good piece of media and see if it loads. If it does, the original cartridge is
faulty and should be discarded.
6. Check if another DAT drive of the same model will accept the cartridge. If it does, the original
drive may be faulty. Before calling customer service, please check that the tape drive is responding.
