Zane,
Do you stay with DEC OEM Model NUMBER on replacement?
What utilities exist to help identify drives to a MicroVAX?
Can I "dummy" some CYL/SPT/Hd count and hand it to the MicroVax and have the
OS Come in later and claim its an RD5? something provided the figures match?
Like, Whats the difference between a Quantum Q-540 and a DEC RD52?
Since Allison Parent mentioned that the RD52 was a Q-540, I have looked it
up in "The Hard Disk Technical Guide" by Micro-House. All the details are
there.
If I were to Find a Micropolis or CDC drive that fit some larger DEC
equivalent on CYL/SPT/Heads MFM ST506 RPM etc what would stop me from
generating a workable drive profile?
Anyone done this?
I have successfully and without problem formatted both Maxtor XT2190 and
Priam 519 drives that had been in DOS service on a MicroVAX 2000 using
Test 70. It appears that if the CSH numbers equate to an RDnn number's
figures that it is assumed to be one.

My view is that I'd never overwrite an original distribution kit -- I'd
preserve it and probably back it up. But I may well install a newer
version of the OS (given suitable licenses) on the machine. I'd attempt
to back up what was already there first, though. That's because I _use_
these old machines. For a museum exhibit, as you said, you want to have
contemporary software.
I've been known to pull the hard drive that came with the machine, and use
a different harddrive. Did this with the VAXstation 3100/30 I've got.
