Actually, the extended qic-80(dc2120-ex) tapes hold 384MB uncompressed. 
I don't know why 384 but that is all I have been able to get on the
tapes that I have used, they label them as 400MB tapes.  

The status command didn't provide much info on the tape, in fact it was
the same for both types of tapes, regular and extended.

% mt -f /dev/ftape status
drive type = 8423552
drive status = 0
sense key error = 0
residue count = 0
file number = 0
block number = -1
gstat = 1000000
