I am currently dealing with this very issue. Here's the scoop as I know it:
an RQDX3 can handle the Maxtor 2190 (RD54), but it has to be a later
revision controller. I was told it has to be rev F3 or later (ours is C3).
I tried to do the format with our controller, with no success. By the way,
you have to get your hands on a special diagnostic tape to do the formatting.
You can upgrade an existing RQDX3 by replacing two chips: calling DEC will
result in them telling you this has to be done by a field service guy or by
sending in the board. After much calling I found out you can order the parts
from Dec Direct, but you have to tell them they are unlisted parts. The
part numbers are 23-339E5-00 and 23-340E5-00. You can call Part Number
Assistance at 603-884-5000 to verify this, that's how I found out. We just
placed the order and haven't actually done the upgrade, so I can't comment
on how it works.
