The answer is yes but the drives have to have the propper low level format.
That low level format cannot be done with a PC.  It can be done on a Qbus
system with RQDX1/2 controller and XXDP.

The OS however expects only standard drvies.  

RD50  == ST506
RD51  == ST412
RD52  == D540 (qunatum)

Other drives that have been used were

RD31 == ST225
RD32 == ST250
