currently i have 3 hard drives in my rig, my problem is that one of them is clicking and making iTunes randomly skip while playing, some time rendering a song unplayable. It also makes other random programs skip, its annoying as hell when im fighting an enemy on WOW and i start skipping and die. I need to know what i can do to tell which one it is, short of running the rig with only 1 drive at a time. Since i only have windows installed on one drive that limits myself. I believe i know which one it could be, i had an oem one sent to me from newegg and i found it delivered in my back porch. The box was a little to big to fit under the fence, so i think the driver dropped it from the top, a fall of 4-5 feet.
