When attempting to add more songs to my iTunes library, I keep getting this error. I have repaired permissions, restarted, and clicked the option to ignore ownership on the volume but nothing helps. And it's not just one song. It happens regardless of the song or artist. Sometimes it happens on the first song when I start copying, sometimes it has already copied several successfully before it stops. BTW, I have the latest version of iTunes and Tiger. I also am using my external hard drive to store my music instead of the internal on my ibook.
