1. Be sure no loose connections (on page 58) exist.
2. Refer to the drive documentation to be sure cables are connected as required.
3. Be sure the cables are working properly. Replace with known functional cables to test whether the
original cables were faulty.

Action: Refer to the Troubleshooting DAT Drives white paper for information on DAT drive sense error codes.
Search for it on the HP website (http://www.hp.com).
DAT drive error or failure occurs
Action:
1. Be sure drivers, software, and firmware are upgraded to the latest revisions.
2. Clean the drive at least four times to be sure that the heads are clean and to eliminate dirty heads as the
possible cause of the failure.
DAT drives require cleaning every 8 to 25 hours of use or they may fail intermittently when using
marginal or bad media. Be sure you are following the proper cleaning procedures described in the
device and server documentation.
NOTE: New DAT tapes may contain debris that will contaminate the DAT drive read/write
head. If using new tapes for backup, clean the DAT drive frequently.
DAT drive is providing poor performance
Action: Be sure the drive is not being used to backup more data than is recommended for the drive. DAT
drives are designed with optimum and maximum data backup sizes. Refer to the drive documentation to
determine the appropriate data backup size for the drive.
