Macbook Grinding Noise If moved While Disc Spinning

Really Apple, was this necessary? If you pick up a Macbook while the Combo drive in a Core 2 Duo Macbook is spinning, you can hear a grindy sound as something is hitting the disc or drive while it's spinning.

It's because the bottom of the Macbook flexes and hits something going around and round. Don't try it unless you like shavings of some sort in your Macbook.

I'm going to see what Apple has to say about this. Anyone out there in Internetland knows anything, leave a comment.
