No, I am correct. there is no formatter for RDxx drives under RT-11.
XXDP does it really well but that is NOT RT-ll.

There is a lot of work but writing a utility to format a RD under
RT-11 is possible, though if you have the tools and info to do that
you also know XXDP is available.

Actually I've never used a RD larger than 31mb on an RT11 system so the
SET DUn would not have come to mind. Why no big disks? I have MANY
MANY RD52s and an RD53/54 would be VAX fodder.

Also while RQDX3s are RD54 aware, some of the RQDX1 and 2s are very much
unaware of the RD54 and will produce errors.
