I have a iMac version 10.6.8 I noticed the size of the hard drive in red. clicking on it, said my S.M.A.R.T. disc was failing. I tried to do a test on the hardware by inserting a DVD instal disc then did a restart while holding down the "D" key, now all I have is a gray screen showing the apple and a spinning wheel. I cannot eject the disc from the super drive. Any suggestions on ejecting the disc and can a new S.M.A.R.T DISC be obtained or do I need to replace the motherboard?
Thanks,
