My iTunes library is nearly 100GB and it's taking up nearly half of my entire internal hard drive so it's time to stick it on an external HDD. I've got the drive all ready, I'm just not sure how to make it happen. I know I go into the Preferences, then Advanced and change the iTunes Folder Location to the external HDD, but what are all the steps after and in-between? Don't I still need to delete the current folder on my system after it transfers? Do I have to reimport everything after it transfers to the HDD? If someone could walk me through it, I'd really appreciate it. I remember doing this a couple years ago and decided to go back to the internal drive because I did something wrong, had to reimport all the songs, and lost a few in the process. I also believe it started asking me to authenticate every single song I wanted to play. How can I avoid all of these mishaps?
