Oringinal Article: Users are experiencing issues when attempting to import tracks from compact discs to iTunes. The disc unmounts and does not complete the importing process requiring the user to eject the disc and reinsert it each time (when it then works). The issue does not appear to be related to a type of import format, nor is it related to permissions problems.
Apple Support Discussions user "ScuseMe" reports:
I insert a CD with iTunes open. iTunes mounts the CD (listed under Devices), queries the Gracenote database, gets the track info, then asks me if I want to import the CD. If I click on OK, the CD is unmounted (but not ejected) and the import does not take place. If I then eject the CD and repeat these steps a second time, the import works successfully. I had 4 CDs in a row exhibit this strange behavior.According to most of the other accounts on this thread, the CD unmounts just after its query of the Gracenote track database, though it is not clear whether the issue is related directly to the query process. Apple does not appear to have a fix for this issue yet.
Set iTunes to "Ask To Import CD" (Preferences > General). When the dialogue box pops up, you should be able to ignore the import and have the disc still appear in iTunes.
Let Gracenote query the tracks and wait for the information to load. Once it is loaded, press the Import button manually. Also, try disconnecting from the Internet and import your discs. Then reconnect and select all your tracks. Choose Advanced > Get CD Track Names from the iTunes menu bar.
