Disabling HD's when not in use?

[Defy Belief]

Hi guys, is this possible? Currently re-installed my 2 x 1tb hitatchi drives, but the noise is driving me nuts, it's a new build and on my previous mobo + cpu (Crosshair III + 955 BE) the hard drives were silent, and only starting moving when I opened them (They're storage drives so barely accessed)

Now i'm on intel they always seem to be moving, and they are pretty noisy, I like it quiet, is there a setting to do this?

Kinda like a speedstep for hard drives..

I looked but it just said hard drive in the advance power management settings, but I have 2 plus one ssd and didn't know what it'd effect if I edited it.
