You need a little flexability here. I have a machine that
is hard sectored and used 8 holes per sector.

It does need retiming and pre-comp added back in.
Still, just a software issue. I like the DSP because
it can actually analyze the particular media used
and generate a more exacting pre-comp than even
the best controller can. This would be great for
archiving since the recreated disk can be better
than the original.
