Hey everyone, I went to open a pdf in Preview when a blue screen with the spinning load indicator appeared. It stayed on this screen for about 10 minutes then I manually shut down with the power button. When I went to restart the flashing folder with a question mark awaited. I attempted to select the startup disk with the option key but only got the mouse cursor. Inserted the Snow leopard disk and attempted to select the startup disk that way but my hard drive would not show up. I can still hear my disk spinning but I am assuming it has failed. Before I go out and buy a new disk tomorrow I am going to attempt to load it as a target disk from a Imac at my university but I want to make sure that it is the hard drive and not some other issue. Any other thoughts?
