a week ago, my black macbook froze, so i held down the power button until it shut off. went to start it back up, and i got the blinking question mark. all of the startup options (hold x, restart pram, open firmware, ect...) failed. plus, i'm getting the seek arm click of death. i'm trying target disk mode using my ibook g4 as the host, but i can't get the hd to show up on my ibook's desktop. any tips? or am i completely screwed?
