My first thought (and I haven't yet read other replies) is that you're
re-inventing the wheel.  Disc controllers and DFSes have error-
correction hardware (CRC checks) so you can be sure you've read the
original disc correctly.  Why do you need to go lower-level than that?

If you can read all (10 x 256 x 80) = 200k bytes of a single sided 80
track DFS disc into a file using the disc controller without error,
isn't that file guaranteed to be an exact copy of the original disc?
