CRC error in exchange backups

[Richard_Cheung]

Hi all

On a server running windows 2000 sp4, exchange 2000 sp4 and backup exec v9.0, I have recently started getting CRC errors (0x00000017) on exchange backups.

There are errors in the event log about BackupExec Devices error - unload status retry - error_not_ready.

I have checked and this does not occur if I run a file backup by itself. I am also able to run a NTBACKUP of exchange without errors.

What would the problem be? I am guessing it isnt just teh scsi driver etc because if it was, then the same errors should occur if i was doing -any- backups to tape, including files, but i do not get these errors on file backups.
