The error I cant get rid of, and that is crashing my whole backup schedule is E6096 Media Error. Even though there are 3 more drives available, any job that attempts to use the one bad drive or tape will time out and cancel, so I lose about 25% of my jobs. I have tried 5 new batches of tapes. Replaced the scsi cards, replaced 3 tape libraries. Loaded all service packs and bios updates. I am running Arcserve 2000 Sp3 on Windows 2000 SP3. Using 2 MIniexpress Libraries (Overland) with Quantum super DLt drives. Overland has worked with me through all the possiblities, even exchanging 3 new libraries. I have to say that it is a Arcserve problem. Anyone seem to have on and off media errors, when you know the media is good?
