Backup Exec 2012 SP4 with all patches.
When running a verify or restore for a duplicate or backup job that spans more than 1 tape the job fails with:
"An inconsistency was encountered on the storage media in Tape drive 0001. V-79-57344-33994 - The data being read from the media is inconsistent."
The job fails once it loads the second tape in the set. Restores of data on the first tape are successful. No encryption is used, happens both with and without compression. Using symantec drivers. Running tracert during the job shows the second tape is loaded and begins to read then after several minutes backup exec ejects the tape and fails the job. Tried setting the registry key to disable Fast File Restore with same result. Happens with multiple tapes both new and old and multiple jobs.
