Hi there, More info is needed.
* What are the messages in your activity log? * What OS is it attached too? If AIX, check the errpt. If Windows check your event viewer. * How long do they work for after you make them available again? Do they break right away as soon as they use a tape, or it is specific tape(s) causing the issue. Bad Tapes can cause weird things to happen. * What kind of drives are they, and what kind of library are they in? Lots of things can cause a drive to go off-line. ----- David N.
