Well I found an error message that is what appears to be the
cause of the drive dropping off line, it is an error that our
NT server is getting from a file that is a MACintosh dump file.
This file is giving the Netbackup software an error of access
denied and is then causing the drive to drop off line.
My netbackup software is V. 3.2 and I have not yet loaded the
very latest patch.
I already have the "skip" feature line in the conf file.
