Is it correct that RX01 format floppies can be
created from blank
floppies with a standard PC floppy controller (or at least some
controllers / motherboards, depending on the controller chip) while
RX02 format floppies cannot?
Yup. The RX02 ("double density") use a whacky MFM scheme (with some
code substitutions) for data with FM sector headers. Not doable at all
with a standard PC setup. RX01s are pretty much stock FM.
