Formatting disk on rt11 - test-drb@ccmp.vtda.org

...
 How can I format a rd54 disk on a rt11 5.3 ? 
You can't.

...
 (disk & floppy are on RQDX3 controller)

Doing something like

.FORMAT DU0:

i get "device not supported, ...) 
Yep, because the FORMAT code doesn't truly know how to format an RD
series disk.  The disks are formattable, but you must use the XXDP
diagnostic ZRQC??

...
 P.S. Booting from DU1: works, so the controller &
driver should be OK.
Trying accesses to DU0: I see the LED of the disk drive on. 
The drive can obviously be referenced, but won't be usable until you
have it formatted.
