  The modified XT-2190's (XT-2190 D) has a lower current surge on startup and
acoustic damping on the positioner. I believe the logic boards are identical.

  Your problem could be a number of things, including jumper settings on the
drive, defects on critical sectors, or formatter problems. I've had maybe 20
2190's over the last few years, all of which have formatted fine for DEC use.
I'm using the PDP-11 formatter for an RQDX3. It seems you're using TEST XX
on a MV2000, which may be different.
