On the 2000 TEST 71 will check the disk and tell you what it is, TEST 70 will format it. Perhaps you could try those commands to see if they also work on the 3200.

Should be an M7620 KA650 CPU in a BA23 box with an M7168 / M7169 VCB02
QDSS video subsystem. The storage controller should be an M7555 RQDX3.

Manual available here:

If you could swap a Q-Bus PDP-11 CPU and memory in for the KA650 VAX
CPU then you could run XXDP ZRQCH0 diagnostics to format the RD54 on
the RQDX3.
