Hi. I'm trying to back up my HD onto my ipod for install on my new PB HD. I want to back up everything except music but i cant find my music file to delete it. I won't have enough room if i back up itunes as well (as it's on the ipod allready)
if I understand what your saying, you want to delete the music from your iPod top free up space? If thats so, then just delete the music in iTunes, and that will free up the space you need.

An easy, safe way to erase the iPod without actually erasing your music is to create a new playlist, don't put anything in it, and set up the iPod to sync with that playlist only.
When you plug it in, it will replace all the music with ... nothing.
Then mount the iPod as a removable drive, and put your data files on it, transfer them to the new Mac, and then reset preferences in iTunes to use the regular playlist again. Plug it in, it will load all your music.
You will need a hack program to move the music from the iPod to the new computer, there's a bunch of 'em on VersionTracker and MacUpdate.
By then all your files and all your music should be on the new Mac. You may need to adjust permissions on the transferred files, or not.
An easy way to prevent that is to set the checkbox "Ignore Permissions on this drive" before you copy the files you want to transfer.
Read Help in iTunes and iPod Help for details of setting up the playlist, using the iPod as a HD, and syncing manually or automatically.
