Grinding, scratchy noise from hard drive area

[Politis]

I like my MBP 15. I bought it late 2010.
But when I work on the internet, or move around Google Earth, it produces an intermittent, occasionally constant grinding, scratchy sound that seems to come from the area to the right to the trackpad.
It is not the speakers. There is no overheating.

Any ideas? Can I run a check to find out what it is?

Could definitely be your drive. I've seen them going bad in MacBooks still under warranty. Get backed up, if you're not already.
