My new build (6 months old) has been making a very strange noise since I made it.
The noise, I suspect is the HDD, seems to only really happen when playing games off the hard drive, or streaming films/ tv shows (temp files for Chrome are also stored on this HDD). The noise also occasionally happens when generally browsing documents on the PC. It also seems to stop when the HDD is disconnected.

This is the noise - https://docs.google.com/file/d/0ByzAuBcUBnNBOVVvZkRyR1h1aGc/edit?usp=sharing
The noise happens once at about 4 seconds in.

Does anyone have any opinions on the noise?
Does anyone agree that its the HDD?
Do you think it could be damaging the drive?
Do you think that I could get it replaced under the warranty?

Thanks for any help given, Jordan.
