There is (T)MSCP, the (Tape) Mass Storage Control Protokol.
It is a
standard way to interface disks (and Tapes) on DEC Uni- and QBus (DSSI)
systems. If your disk adapter speaks MSCP, it will work regardless of
the actual disk type. The reference to the MFM disks is a reference to
the RQDX[123] adapter, that is a MFM to MSCP adapter...

Yes. I used the
DQ686 with a KA630 and a KA655 under NetBSD and it
just worked.
Looking at the compatibility listing, it didn't look like it
supported much else other than the standard MFM drives. It's good to
hear that I was wrong. Perhaps you
should do a low level reformat and bad block scan of the
disk? You know the magic words to invoke the controller setup?
That would probably
be a good idea. I don't know anything about it's setup.
INIT (via RESTART button)
Then type into the boot prom:
D/P/L 20088004 80000001 <cr>
D/P/W 20001f40 20 <cr>
D/P/W 2000146a 3FFF <cr>
S 200 <CR> (or "S 218 <cr>" if you have GPX graphics)
and you will see the adapter menu setup. Reformat the disks, do a bad
block scan and revector the bad blocks from the errorlog.
