Unknown Error Occurred - HP DAT 72 USB

We're having a problem with backing up our SBS 2003 using BE 10 5629, SP3.  We keep getting the following error:
 
Final error: 0xe00084f4 - An unknown error has occurred.
Final error category: System Errors

For additional information regarding this error refer to link V-79-57344-34036
 
The link says to make sure we're using the latest driver, which in the case of the DAT 72 USB, is not provided by Symantec, but by HP (for some reason).  After searching the forums, it looks like we're not the only ones having this problem.  Backup Exec is reporting Tape Alerts, but HP's tape tools passes every test we give it (even on the phone with HP).  HP replaced the drive anyway, and we're still getting the same error(s).  The driver version from HP that we're using is 1.5.3.2, and yes, the drive is listed as being compatible with BE 10d (when using the HP driver)
 
I just made a couple of changes in desperation (disable write SCSI pass thru mode, enable RAS Auto Connection Manager) but I'm wondering what to do next.

Anyone?  We're still getting tape alerts.

My 0xe00084f4 Solution

This is how I finally fixed the same error after a lot of effort and failed attempts.

Test your tape drive to be sure it works outside of Backup Exec. I had an HP drive. Go to hp.com/go/tape. Find the link under "value added software" for "Library and Tape Tools", click that link, download the software. L&TT is a free diagnostic tool for HP tape drives and libraries. If it works, the problem is within Backup Exec. (I was using 12.5 with the very latest drivers, literally posted this week).

  1. Disable the tape drive in Backup Exec (right click on it)
  2. Delete the tape drive in Backup Exec (right click again, need to disable first) This must be done in Backup Exec! Doing the same in Windows Device Manager and rebooting did not fix the problem.
  3. Stop all the Backup Exec services (I did this with services manager & confirmed in Windows Services)
  4. Start all the Backup Exec services
  5. The tape drive should be re-detected.
