Some PCs will write SD, of course, although I think far fewer will write SD 
and 128 byte sectors.

I don't know about the Vixen. The OCC1 uses what seem to be stock drive 
chassis but with custom logic boards that get power over the same cable as 
data. I get the impression that there's nothing special about the 
signaling, though, and so it's likely possible to run different drives 
(which would include 3.x" units) if a suitable adapter were to be wired up.
