So I want to upgrade my 250GB HDD in my MacBook Pro but have been holding off for one big reason...iTunes. I have my iTunes library set up the only way i've ever done it. All my albums are playlists. Does anyone know if was to get an external HDD and make it a time machine, if it will save the playlists and files in iTunes, i know that time machine makes an image of your disc, but to what extent? I want to do this so i can just backup from time machine when i install the new HDD. I don't want to have to go through and remake all the playlists again!!!
