If this is purely a software problem(i.e. it's because the 800K formatting
left some garbage info behind) and not a hardware prob (damaged the disk
physically) then try formatting it on an IBM drive as a 1.44m (or 720k?)
and then reformat it on the mac.  Basically, you want to remove whatever
garbage the 800k formatter left behind.
