I don't believe that this is correct.  The Apple ][ on a 3.5 uses 512
bytes per block, while the Mac uses 524(?).  Anyway, more than 512.
The mac places file attribute bytes in each block of a file so that
the file lise can be reconstructed even if the directory is
destroyed.  Bit copy mode may work anyway, but only because the
encoding mechanism used for the media is the same (IWM).
