So I have a portable Western Digital hard drive that contains the vast majority of my music files. A I have it now, I can bring the songs into iTunes while the hard drive is connected to the computer and load them on to my iPod. If I then remove the hard drive from the computer and then later reconnect it, iTunes is unable to register where the files are stored. Is there a way that I can make iTunes register the portable hard drive and remember where to find my music files? I'd like to be able to use iTunes as my sole music player on my computer. Thanks in advance for any help.
