Both should be able to be used unless the Quantum somehow has a broken 
scsi protocol, which isn't likely.

Consult your equ to dmesg and see what device it was found at when the 
machine was last booted.  Then, using mt, check that device and see 
if you can control a tape inserted into those drives.  Ditto the 
changer if there is one, using mtx this time.

If mt works with the quantum, the rewind the tape in it, and fire off 
a session of amtapetype -f /dev/whatever -e known size of drive, this 
will get the true capacity of the drive.  But... Turn off any 
hardware compression first else amtapetype will probably complain, 
and return a tapesize thats obviously smaller that the rated size of 
the tape with compression turned off.  The data src while testing 
is /dev/urandom, and that will expand in a hardware compressor by 
5-15% instead of being shrunk.  In any event, amtapetype will 
probably take several hours to run as it does two, till the tape is 
full, writes.  Don't use a tape with something precious on it.
