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). If you can't find a
ripping tool which handles read offsets, you'll have to align
audio data in the files by hand.
