I am getting a media read error 85 when trying to restore some files from an 
LTO-1 tape.  I already swapped tape drives to rule out a bad drive. 
 
This is on Netbackup 5.1 MP6 Windows.  This system is up for legacy restores 
only.  The backup was made on a media server that no longer has drives 
attached.  I connected a standalone LTO-1 drive (fairly new) to my master 
server and configured fail over restore server to point to the master.  The job 
starts to run and fails.  I already checked the number data buffers and size 
data buffers to confirm they are the same as when it was backed up.  The tape 
has been frozen also due to the errors from the failed restore attempts.  I am 
not sure if this matters or not because I still get the same errors.  Also the 
tape was going to expire so we ran the bpexpdate and extended the retention 
before it expired.
