Macbook Pro Internal Noise

[MBPCAG]

I have had my Macbook Pro for about 3 days now and there is a weird noise coming from the inside. Mainly when I tap on the bottom right of the laptop I can hear a clicking noise. I can also hear it when I tilt it from side to side and it sounds like it is coming from the disc drive I was wondering if this was normal?

Hey,
I noticed this when I first got my MBP its the sudden motion sensor in the HDD parking the heads with any movement. I have noticed that they are rather sensitive and click with little movement. Nothing to worry about however.
