Strange noise on a 2011 MBP - sample inside

[Benj2000]

Hello everyone!

I just received my new MBP 15 and I am a bit disappointed par a little sound coming periodically (approximately very 15 sec) from my HDD (7200 RPM) like if the heads of the hdd park by security but my MBP is on my desk and doesn't move. This little click is really different from a normal working HDD noise and happen even if I do not use the MBP (idle)

Here is a sample :http://www.megaupload.com/?d=Y1RZ9QAI

Is it a normal noise or do I have to send the MBP to apple?

Thanks a lot for your help!

you seem to have much more problem than I.
Do you think this hdd noise is abnormal?
