So I'm new to having a mac and just bought my Macbook Pro Unibody 15 inch a few weeks ago. I'm having a problem with my superdrive. It won't insert a disc I put in, as if it was dead. When I turn the computer on, it doesn't make the spool up noise as usual. I've only used it a few times and burned a few cd-r's. It seems that it went down hill after the new update for 10.5.8. I have also checked my system profiler and it says that the "ATA This system does not contain any ATA devices. If you have any ATA devices installed, please check that they are connected and powered on." And for "Disc burning No burning device was found. If you are using an external device please make sure that it is connected and powered properly." The big issue is my superdrive practically rendered useless and I can't reinstall the os if it's software related. I have tried smc reset and that didn't work. If someone can help please. I have purchased this computer from best buy with accidental warranty plan. I'd like to know if this is software related or hardware. Thanks!
