  Third-party hardware? (DDS tape) 
 The Question is:
 
I want to use Sony 125P DDS-3 Tapes on my TLZ10 drive. If I use a brand new
 tape and use the following commands
$ INIT/MEDIA=COMPACT MKA500: TEST
$ MOUNT/FOR/media=compact mka500:
$ backup/media=compact/ignor=label dka100:[000000...] mka500:
and look with
ABF008/81&gt; show dev mka500/full
 
Magtape ABF008$MKA500:, device type DEC TLZ10, is online, allocated, deallocate
    on dismount, mounted foreign, record-oriented device, file-oriented device,
    error logging is enabled, device is busy, controller supports compaction
    (compaction enabled), device supports fastskip.

it shows Density DDS2! What must I do to use DDS3 density?

 The Answer is:
 
  A potentially a similar problem was seen with the Compaq SDT-10000
  DDS4 drive, and involved a requirement for a new MKDRIVER in V7.2-1.
  Your problem may or may not be related.
