Not at teh console boot level. VMS will idenify them as weill MDM diags.

NONE, RD52 is what dec calls a Q-540.

RD54 is Maxtor2190, look that up.

Now, heres the nasty part. Of the RD52/3/4 disks there are Quantum,
Micropolus and MAXTOR drives non DEC branded. They are the same. They
are also different! The NON-DEC supplied are not formatted to match the
RQDX2/3 controllers. So if you find some D540s, you may also have to
format them... you likely don't have diags to do that. So even with a
pile of them your still not ahead.

Solution: prevail on someone that bas a Qbus PDP-11 with diags that can
format the drive.
