im going to reformat my computer soon. what i'd like to know is will i lose my itunes info? ive spent several hours adding album covers and changing the titles of the songs to be consistant with teh rest of my ipod and i want to know, when i reinstall itunes after reformatting, will i have to redo all this work? or should i copy the entire itunes folder onto my external harddrive and copy it back to my computer at a later time? or does my ipod save all this info so after im done the reformat i can just plug in my ipod and all the info will still be there?
