Actually, I was commenting on the error someone else was reporting -- even
still, the ability to turn on or off hardware compression ultimately depends
upon whether or not the drive has hardware compression ability in the first
place.  The point being that some (most) 7980's do NOT have compression (I
believe the actual model is 7980XP that has compression ability).  So, if
you received a tape from someone that stored it WITH compression, you're
basically SOL if you want to read it on a "normal" 7980.

 Not sure if this is what you wanted to know or not, but HP has the routine
called DEVCTRL
in the Telesup account that enable/disables hardware compression.  I know it
works on DLT, DDS drives, but not sure on a 7980 drive.. It should tho.
