The format of the bitmap is documented in an AmigaMail article, contact
CATS for back issues. It turns out you don't need to know the format for
the bitmap because you can just mark it as "bad" in the rootblock when
you are done and after uninhibiting the drive the disk-validator will
run and write an updated bitmap on the disk for you. Simple as pie.
