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. Latest firmware indicates a defective tape, or head clogs occur regularly Action: Replace the tape. Other errors are occurring Action: Replace the drive. DLT drive problems Server cannot write to tape Action: • If the drive cleaning light is on, clean the drive. NOTE: DLT cleaning cartridges are good for only 20 uses. If the cleaning cartridge is near that limit and the drive cleaning light is still on after running the cleaning cartridge, use a new cleaning tape to clean the drive. • If the tape is write protected, remove the write protection. If the tape still does not work, insert another tape into the drive to see if the original tape is faulty. • Refer to the tape drive documentation to be sure the type of tape being used is supported by the drive. • Check each tape cartridge that has been used in the drive to verify its condition and inspect its tape leader to verify it is not damaged and is in the correct position. After you locate any bad cartridges, dispose of them. A working tape drive may drop its leader when using bad cartridges, indicating that they need replacing. If bad cartridges are found, you will need to inspect the DLT drives leader assembly. o To examine the cartridge take-up leader, tilt the cartridge receiver door on the front of the drive and look inside to see that the drive leader is connected to the buckling link-hook.
