I have a rev. A G5 dual 2.0 and when I insert cd's or dvd's in the superdrive, it seems to have troubles recognizing the disc. There's nothing wrong with the cd since it loaded up on a G4 dual 1.0 at work and it works perfectly fine on my iBook G3. I'm wondering if there is something wrong with my superdrive. The dvd's I use are by Maxell, so they aren't that cheap. The superdrive reads it, but takes some time. The regular cd's that I load in the superdrive is a no name brand but like I said, it works on all the other mac computers I use. I also inserted an IBM brand cd in the superdrive and it didn't recognize the cd at first. The second time I inserted it, it recognized it. Anyone else experience these problems? I'm just wondering if it's a hardware issue with the superdrive. Thanks.
