Compaq 40/80GB DLT drive

[Mary Carlos]

Hi:
I have a Compaq 40/80GB DLT drive. I am getting illegal commands when trying to erase or format a 20/40GB Tape on a 40/80Gb Drive. It will erase and write to a 40/80Gb tape without a problem.
It is attached to a Compaq Proliant 1600.
It has run in the past.
The difference is that I had to re-install ARCserve 7 because the DS.nlm had to be replaced with a new module.
Does anyone have any ideas as to what my problem might be the problem?
Any help would be greatly appreciated.
Thanks,
Mary

It sounds like a software issue, but to be sure you could install HP LTT (www.hp.com/support/tapetools), and collect a support ticket. See if there are any new entries in the "Event log" after a failure. The entries also have a Power-on hour (POH) field that you can compare to the current POH to see how recent any error events are.

You could also run the HP L&TT read/write test, or the DLT acceptance test on the tapes in question, to see if there are any problems writing to them.
