Hi guys, I have a last gen. Mac Pro, attached is the system profiler view. I haven't ever really used CD's in its dvd-super drive but I have started to recently. It Wont read them, just makes a strange noise, Im guessing searching for it, and then either stops, ejects itself, or posts a error saying it isn't readable. From the tech speck it should be, they are CD-R. I have put in and burnt lots of DVD's etc so there is no problem with that. Has anyone had a similar problem, is it possibly a problem with the lense? I know that CD & DVD have different reading intensities. Or could it just be that it needs a good clean? I took out the DVD drive and it was dust as can be, gave it a clean, but would prefer not to open it up. Any suggestions?
