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. -- --Chuck McManis Sun Microsystems uucp: {anywhere}!sun!cmcmanis BIX: Internet: cmcmanis@Eng.Sun.COM These opinions are my own and no one elses, but you knew that didn't you.
