I'm having this problem VERY often while trying to add cd's to my itunes library. My cd's are in pretty good shape and all them were able to be added to my crappy IBM that's five years old and using an old, cheap external dvd reader. I don't really mind if it can't read some of these songs, but it CRASHES the entire crappy mac. I have to go over to another program, force quit itunes (this is where I am told that itunes is not responding) then wait a while and eject the disc. Why wouldn't it just move on to the next song or something. This is ridiculous that a computer barely a year old is CRASHING from a read error.
