i have already taken off the top and checked to see if the cords are connected. they are. the hd makes no noise at all. its silent and still. nothing comes up at all. only that little corner led. in hyperterminal it just loops the checking and the 'flying penguins' but nothing pops up. so could, (please!!!!!) the cable just gone bad? if so can i go to like best buy and buy a replacement? or is it more complicated? what cord EXACTLY do i need? thanks to all!
