I've never used Time Machine. Is it possible that your Time Machine backups are being stored on your internal HD?
I thought that Time Machine backups had to go to a HD only used for the backups, and you couldn't store other items on it.
Also is it possible that you just copied your iTunes, photos, documents to the external HD, and didn't delete the originals from your internal HD?
Did you empty your trash, clear yor caches?
Also, this forum is for non-Intel based Macs. You might get more help in the Intel-based iMacs forum.
