Ok so I recently got a Macbook and am in the process of switching my library from my G4 to my Macbook. So while doing this I put my whole library onto my external hard drive and start the switch. I did it the right way also by changing the location of the library in prefences and then consolodating the library and then when I switch back to the original library it says in iTunes that every song's origingal file cannot be found. Is there a way to reverse this? Any help is great. Thanks!
