My macbook was working for most of today until when I closed the screen down for dinner, and when I kame back I noticed that it was frozen so I shut it off and when I turned it back on, I noticed that it was stuck on that grey screen, so I tryed 4 more times and no luck, so I stuck in my Leopard DVD and ran disk Utility and the HD was marked as diskos02 and wouldn't read me thee space free or the space used dffdfsdf˙df and I wasn't able to verify nor repair the disk. What made it weird if it was a dying hd was that it didn't give me the typical HD symbol with the question mark. Do any of you guys have any suggestions?????
