Thanks for looking.

That standard is only capable of marking bad sectors. It doesn't have the
information on where the bad sectors were remapped to. I took a quick look
at the DSM image. It looks like cylinder 511 is where the controller
tables are. This cylinder does have a different format. The data didn't
match this standard.
