Okay guys - 500 pointer.
We have a backup server with a Compaq DLT7000 tape drive. Recently the drive failed, and we have just had a new replacement fitted by Compaq. However, when we now try to format a tape in the drive we are getting an error which says "Unrecoverable Data Error" - this is using fresh tapes, straight out the box.
Have I missed something, or is the new drive fubbared as well?
