VMS: problems with INITIALIZE MUC6: (TK50)

Hi,

this is a followup to the problem I'm having formatting a TK50 drive
with a VMS filesystem, needed to create a diagnostic tape. I am on
a VAX 6400 with VMS 5.4 or 7.2 (dual boot so to speak :-), nether
works. I do

$ INITIALIZE MUC6: ELAN

When that runs the tape scrunches and spins happily until suddenly:

%PBC0, Port is Reinitializing ( 45 Retries Left). Check the Error Log.

%INIT-F-VOLINV, volume is not software enabled

then in the error log I find what's attached below. This time, I
believe the critical entry is there. Could someone help me
interpreting this? I suppose it might just have a data error,
but this should really not make the whole thing stop. I had
several warnings when I wrote a tape with this drive on a
uVAX-II with NetBSD, and it still went on writing it all. So
is there an easy fix?

Could it be that the TK50 tape doesn't play well with the TQK70
controller? Would it be better if I hooked the TK50 to the DEBNT,
but where on the backplane rear do I connect this sort of thing
and how is the IDC connector wired on the VAXBI side?

thanks for helping out,
-Gunther
