You can turn HD off in power options, after a certain time of inactivity.
Don't forget to change it back to "never" or whatever suits you.

Listen to where the noise is coming from, may have to take the case cover.

It would be cool to find a program to turn them off individually so I could turn off the noisy ones I rarely use!
Does someone know about a program to do that?

Are you talking about fans or hard-drives? You don't want to pick which fans you shut off yourself, and if you have hard-drives you don't use, take them out and make them external.
