If so, just go to control panel/sounds and audio devices/sounds, and make sure "start navigation" is set to "none".
I've had my WD My Book for a few months and recently it has been clicking. Its not the click of death and it works fine. Doesn't have any problems. But when I'm doing something on it, whether that be watching a video or listening to music it'll click. Just once. It does it every five to ten minutes. I might just be paranoid since another hard drive died this week D:
