I have a WD Caviar blue 5000. It worked completely fine this morning, then shut it off when it powers on the bios recognizes it but after it passes the bios check screen the screen stays black. The Harddrive is spinning and seems to be functioning properly out side of nothing showing on the screen. I then booted in Ubuntu and much to my suprise it mounted and i have full access to the harddrive and all of its contents. Got any idea cause im stumped.
