Don't think you're out of the woods yet. Send that drive back immediately. Drives don't just click and then stop forever. That is a sure sign that it WILL fail. Just ship it back and get another under warranty. Otherwise, somewhere down the line you're gonna lose everything. I've had that happen to me... trust me, hard drives do not click... EVER.. unless they are on the verge of death. Fans, jumpers, IDE cables, etc have no bearing whatsoever on this.
