There's no reason to spread or believe rumors, when you can plug in the
iPod and find out directly.  The iPod has three partitions.  The first is
the apple partition map.  The second is the iPod's firmware, which is 32MB
long, mostly empty.  The third partition is the HFS+ partition where
iTunes and all the MP3s are stored.

The third partition is layed out like this:

/
/iPod_Control
/iPod_Control/Music
/iPod_Control/Music/F00
                    F01
                    F02
                    ...
                    F19

The music is stored in each Fxx folder with it's regular file name.  I am
currently trying to discover how iTunes hashes the music into the folder
structure.
