   If there really is nothing wrong, often a bulk eraser will fill the bill.
I think radio shack still sells one for about $20.
   The nature of the MAC disk format is much more forgiving in allowing things
like disk/media defects in 'the wrong' place.
   Lastly, when a mfg uses a bulk type of disk duplicator, it is quite easy
and possible to manufacture working disks with either duplicator burns or
intentional media defects.
