I have all my music on an external HD that I've used for a few years. I told my old computer (1GHz TiBook G4 with Tiger) to export my iTunes library, which it did, as a .xml file. Then, I opened that file on my new iMac, and only about 1/5 of the songs were found, apparently. This doesn't make sense to me, as the iMac is connected to the HD when I import the old library. If it makes a difference, the TiBook was NOT connected to the HD when I exported the library. I have the two computers networked together via Ethernet right now, though. Any idea how I can fix this problem?
