I don't know why the resulting hash is different from yours.

Extracting the same audio track with different drives often give
different files, although with the same size. If both extraction
went fine, the same data will be in the file, but shifted and
padded with zeroes. This comes from the fact that the CD-DA
Red Book does not clearly specifies where audio starts, thus
different drive manufacturers did implement different drive
offsets (both on reading and writing).


  We're not talking about ripping audio from CDs.  We're talking about
converting iTunes files to WAVs.  No ambiguity about where _they_ start and
end.
