The drive is, but there is a SASI<->MFM bridge card in there.

My own experiences with formatting the drives is that it should take several
hours to format a drive with the older ROMs, then there's a newer rev that
takes almost twice as long.  We are talking 2-4 hours, not 12, so that's not
your problem.

What might be happening, and this is just a guess, is that there is a jumper
that tells the DOS board (the one with the IEEE connector) if the drive has
4 heads (5 MB) or 6 heads (7.5MB).  If you are using an ST-225, that has
4 heads and the jumper has to match.  I would have expected an error code,
but if your board is strapped for 6 heads, the format will fail right away.
