I get this error in my Backup Exec Logs when performing a filesystem backup using Verison 9.20 Revision 1401. I am specifically not using the Open File Manager. Volume appears fine otherwise, no hardware issues, etc. Are the seriesw of files really corrupt? How does the tape software know? Is the error message to be ignored?

The OS version is 6.5 SP8 with the latest NSS Rev B paches.
