Sure, the WD1772 floppy controller chip in the ST can't handle the data
density. It's only able to handle single and double density, which amounts
to 125 and 250kbits/sec. The density select line is also permanently wired
for double-den... If Western Digital has a somewhat-compatible newer controller
chip that you can use, it shouldn't be too hard to upgrade, but for now,
it wouldn't be easy.
