  23. That method was popular on the old Apple ][ for a while until developers
  24. were sued for damages...Appears that they would burn the hole out around the
  25. outter edge of the disk, and then make sure the drive would never go there
  26. in normal operation.  The idea was that when the user tried to copy it, and
  27. the head passed over the damaged area, it would destroy the read/write head.
  28. Great, 'huh?  Anyway, that's a thing of the past.
