Yeah, there are both the "customer diagnostics" and the "field service
diagnostics" tapes for a Microvax II. Both are pretty lousy tools when
it comes to formatting RD-series MFM drives on a Microvax. At best you
can start out with an already formatted disk and end up with a formatted
disk; at worse you can start out with an already formatted disk and end
up with an unformatted disk.
If you want to format a "raw" drive, the best tools are:
1. XXDP+ on a PDP-11. Boot it, type R ZRQC??, and you're set.
2. A Vaxstation 2000. This is actually the best way if you're formatting a
non-DEC-standard MFM disk geometry, as you can specify
format parameters for geometries other than DEC-standard. And you
don't need any software, the formatter is in ROM, just type "TEST 70"
at the >>> prompt and you're there.
This - and maybe 99% of the other questions asked here about RD-series
hard drives and RX50/RX33 floppies - are answered in a very informative
file at

Whoever's in charge of the port-vax FAQ would do us all a favor by placing
this link in a prominent position in the FAQ.
