I have a home computer (Dell Inspiron 700m with XP) and a work computer (IBM Thinkpad T61 with XP). I have transfer my music library from my home computer to an external hard drive using Edit > Preference > Advanced > Change itTunes Media Location. My home computer can now play my music from this location on the external hard drive. Then I down loaded itunes on my work computer, and I would also like to be able to USB my external hard drive to that computer and play my music library from there. Is that possible? I have already gone to the Store drop down menu and authrorized my itunes on my work computer, but I do not know how to get it to recgnize and play music off itunes folder on the external hard drive. Advice much appreciated.
