Hmm. Non-trivial then! :/
Another problem to consider is how to map sector
lengths that aren't
512 bytes onto modern discs.
Probably not so much of an issue given the speed of old hardware against
modern stuff - multiple sectors could be combined in software on the
modern hardware to represent a single 'unusual' sized sector on the
original equipment at a rate faster than the original host could process
it anyway.
