Correcting Intermittent Failures - Compaq DAT AutoLoader Reference Manual

Correcting Intermittent Failures

If the DAT AutoLoader works only intermittently:
1. Clean the tape drive's heads.
2. Run the Compaq Diagnostics Utility and the tape drive Diagnostics
Utility. Follow the steps listed in the Installation section of this chapter
for the Compaq and tape diagnostics programs.
3. If the tape backup procedure starts correctly but then stops with an error:
a. Use test to check firmware revision level.
b. If the error occurs on the same file or directory each time, remove
that file or directory from the backup list because it may be
corrupted. Correct any errors that you find with the file system.
4. If the tape backup procedure starts correctly, but stops intermittently:
a. Check the DMA, IRQ, and port address settings for conflicts. If there
is a conflict, change the setting or remove the conflicting board.
b. Try using a new tape cassette.
Check to make sure the DAT autoloader has the latest upgrade. If not, upgrade
to the latest version.(Refer to the Compaq website address listed at the front of
this guide for the latest options SoftPaq).
