I'm probably not the first to have this issue, but I wanted to ask the question anyway, because the community is generally very helpful. Since a short while ago, my SuperDrive has been acting very oddly. It will read DVDs just fine. But, when I put in a CD (commercial, audio CD), it will make an effort to read it, three times, but then eject it. It's in a MacBook Core Duo, 2.0Ghz. Here's the System Profiler info for the SuperDrive: MATSHITA DVD-R UJ-857: Firmware Revision: HBE4 Interconnect: ATAPI Burn Support: Yes (Apple Shipped/Supported) Cache: 2048 KB Reads DVD: Yes CD-Write: -R, -RW DVD-Write: -R, -RW, +R, +RW Burn Underrun Protection CD: Yes Burn Underrun Protection DVD: Yes Write Strategies: CD-TAO, CD-SAO, DVD-DAO Media: No Also, in my System Preferences, under the CDs and DVDs heading, I can't seem to change any of the options anymore (started happening at the same time as the SuperDrive issue). This is how it looks at the moment: I'll select an other option from the drop-down menus, but after I've closed System Preferences it must just jump right back, because the next time I open the CDs and DVDs preferences, it's like this again. This leads me to think it might be a software issue (wishful thinking, really), but I've started to believe it must be an actual hardware issue with the SuperDrive. Any advice? Should I swallow, take a few breaths and get a replacement SuperDrive (thank goodness for AppleCare coverage)?
