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.
