According to a recent experience I had with my 2 mini's superdrives, I learned that apple doesn't really support +R media. yeah, it sez it does in your system profiler under About This Mac, but if you go to apple with a problem and they hear that you're using +R, they'll tell you it's your media and that they don't really recommend +R. IMO, if they don't "really" support +R, then they should "really" remove +R from the list of supported media in the system profiler and wherever else they mention it as ok for use in their machines. nk
