Issues with TL2000 using Backup Exec, backup would not run,discovered that tape was stuck in drive. After removing,still not able to backup. Reading forums suggest that the firmware may require updating. Updated the library firmware with no issues, tried to update the drive, first time it failed after 40 mins, re-ran, again took 40 mins but failed with following error :- HE: fatal system error, flashing error on pipe download
Code: D7 22
