I just bought a WD 1TB external harddrive. I want to set it up solely for music and videos that I download, but I currently have no idea how to go about doing this. If anyone can, please walk me through the best option to set up this hard drive for file storage. I don't really care about backing up all my files that are currently on my computer, I just want to use this for music and video storage! Also, how would I go about keeping my iTunes on the drive as well?
