There was some discussion on this on the VCFED forums. Might be worth a
read.

Subject: Re: RX02 rx-01 heathkit 8 inch drive for H-11 ( lsi11 heath case
drive
diff?)
Are you referring to having the H-27 drive from Heath? I don't know for
sure
because I've never seen H27 docs, but the disk
capacity is the same as the
RX01 (256k) and I think the interface was made deliberately incompatible,
likely at the behest of DEC. The version of RT-11 (called HT-11)
supposedly
used a different floppy device driver.
Again, this is based solely on what I've read from various places and not
direct experience (I have an H-11 with a SCSI controller; no floppy; and
it runs
RT-11 no problem).
