Jim,
I have had success formatting RD5x harddrives and look-alikes on an
11/23+ using the "M-11 FORMTR RX50" diskette from DEC. It's DEC no.
BL-FN7AP-MC, CZFNAP0. You used to be able to order it from DEC Direct
at 1-800-344-4825 for about $85.
This diskette contains the "latest" diagnostics for disks, diskettes,
tapes, etc. from the Micro PDP-11 Field Service Test Diskettes. You
might have an old set of those diskettes around (they are sometimes
found with the machines) that has recent enough versions for the RQDX3.
Formatting with the RQDX1 and RQDX3 are not compatible. For a good
discussion of many of the questions you ask, see the file
ftp://sunsite.unc.edu/pub/academic/computer-science/history/pdp-11/hardware/third-party-disks.txt
as well as other files in that directory.
