Check the man page for setfdprm(8) and have a look at /etc/fdprm. There are
several parameters like sectors/track, inter-sector gap, etc. that need to
be set. I've been able to read HP-300 series floppies on an '86 box with
some creative guessing. The general idea is:
1) make sure you have rw permissions on the drive
2) slot your floppy
3) edit /etc/fdprm
4) run setfdprm
Oh, and you need to setfdprm back to the original config before you can use
the drive normally again.
Lotsa luck.

If Heineken merged with Lowenbrau, would they sell Lowneken or Heinebrau?
