I'm getting the error "The data being read from the media is inconsistent" (e00084ca)" during a full backup of one nss volume on my OES2 SP2 server. Everything I've read about the error indicates a problem with the tape drive or b2d disk, but other volumes are being backed up with no problem, including volumes in the same nss pool. This has happened with different tapes and disks, so I've ruled out the backup hardware.

The job has been failing with a byte count of 135 GB (out of 180 GB on the volume), but then the tape itself shows almost nothing written (9 MB) and shows "End marker unreadable" after it fails. Again, everything I've read indicates backup hardware issues, but it's only on this one volume. It isn't the largest volume being backed up.

Any ideas? Thanks.
