Yes, that confused me too. The RQDX3 is clearly capable of
LLFing a floppy. So either (unlikely) DEC specifically do
not allow the right set of commands to LLF an RX50 or
(more likely) that bit of software you have doesn't do it
(although others can) possibly so as not to cut into DEC's
sales of pre-formatted disks.
Sorry I don't know more, the RQDXs are too modern for me.
I don't know for sure, but I really think it's the RQDX3 that explicitly
refuses to format the RX50.
If I just had an RX33 I could easily test this, as I can easily patch
the RSX FMT program to treat an RX50 as an RX33...
