I connect the external hard drive to the i-book with a Fire Wire.
Then, I actually click on the folder on the hard drive, drag it over
to the i-tunes screen [set on library] and drop it right in the area
where the titles go. This unloads all the titles, but the music stays
on the external hard drive. When I play the music, it plays from the
hard drive. If I disconnect the external hard drive, I still have all
the titles on my screen, but if I click one, nothing plays -- because
the music is on the external hard drive, which is disconnected.
If you drop a rather large file, the whole file of titles has to download before you see any titles, so be patient.
Hope that helps.
