well it was the slave drive, i used it for all my media storage. It doesnt click, or make any weird noises, i know on my other HD theres a green light that blinks when it boots up, i dunno if my other HD has a light but looking at the light on my other one its so small its barely noticeable. So if there is one its not turning on, i just think the HD isnt even powering up, but im sure the data on it will be fine. Windows/Bios doesnt even know its hooked up
