VAX COBOL media, and RRD40 difficulties

I don't think they are DEC-designed caddies: the RRD50 and
the later RRD40 are both (IIRC) Philips designs. The caddies
are Philips - they invented the technology (with others) so
I'm not sure you can label them proprietary. They were also
either the first or nearly the first to do something other
than a flip top (like the RRD50[1]). It's hard to follow
the herd when you are riding point ...

I've sent my last spare to another list member today.

I'm pretty sure the KRQ50+RRD40 combo is supported (always
assuming you have not bodged a SCSI-RRD40 to work there :-)).
Unlike WXP, OpenVMS has plenty of crash diagnostic tools so
this could be debugged. But before going down that  path,
I would carefully inspect your bus and make sure that you
are not missing some grant card in there or have committed
some other heinous sin.
