Dying Hard Drive?

What is this noise?

I hope the clicking (near the end) is not a sign of my hard drive dying.

What is it with me and hard drives? Why do they die around me? What am I doing that causes them to keel over?

My machine usually has WoW running … nearly 24/7. Usually at the login screen.

Saturday, May 19th, I logged into WoW to play. After a few hours of play, I heard the clicking noise and my machine would pause for a few seconds, while clicking, and resume normally after the clicking.

Then, one clicking session did not end for 3 or so minutes and I shut off the machine. I haven’t turned it back on yet.
