IIRC, the HP cartridge tapes were definitely pre-formatted ... something
allegedly done only at the factory.  If you wrote on one with a non-HP drive,
it would then be useless in an HP drive.  (IIRC, however, there might have been
a way to re-low-level format them on an HP 9144 or HP 9145 drive, but it 
required an offline utility program and a lot of time.)
