My 5100 maintenance manual is buried, but my 5110 manual says that error
"07" is a CRC error in the ROS. I have notes diagnosing a similar
problem indicating that one possible solution is to remove any tape in
the tape drive before powering on. Seems unlikely that this would work,
but you never know.
