I just got a new Macbook 2.2 SR a few weeks ago. I've been importing my music collection into iTunes. After several discs of working fine, the drive will start doing the following: After inserting a disc, the drive will spin up and OSX will recognize that a disc has been inserted with an icon on the desktop. ITunes will start to get track info from CDDB, and immediately after getting it, the disc disappears from both the desktop and iTunes, and I have to eject the disc and reinsert it to import it. This occurs periodically at first, and then gets more frequent to the point of occurring with every disc I insert. After restarting, it will work fine for several discs, then slowly start recurring to the point that it does it with every disc. I'm concerned. Should I be? Any thoughts on how to remedy this situation? Is it hardware or software in origin?
