How to Use External Hard Drives for iTunes
To store and use your iTunes library on an external hard drive, do the following:
Find and purchase an external hard drive that fits your budget and is significantly larger than your current iTunes library. You want plenty of room to grow into it before you have to replace it.
Connect your new external hard drive to the computer with your iTunes library on it and back up your iTunes library to the external hard drive. The time this takes will depend on the size of your library and the speed of your computer/external hard drive.
