My iTunes Library is stored on an external disk in a folder called "iTunes Library" at the root of the drive. Also at the root of the drive are folders like "Albums" "Singles" and "Mixsets" etc. I just moved everything over to a new external hard drive. I copied everything from one drive to another - so the file and folder structures are identical. The only difference is the volume has a different name. It was Maxtor Music, and is now WD Music. Since doing this, most of my music is missing according to iTunes. When I change the name of the volume to Maxtor Music, everything works fine. Is there anyway to get iTunes to recognize its just a name of the volume change and just play everything? I didn't think it would cause this problem.
