I have an old G4 and it did not have enough space for all my music that I had and I kept all my music on my ipod. I just got an external hard drive and ripped all my music from my ipod to the external drive. However now when I try to go into my itunes prefs and change what folder the itunes reads from it doesnt work!! I have searched all over for an answer and they all tell me to do what I have already tried. Any help would greatly be appreciated! Thank you so much!
