I had an old 40 gig hard drive laying around, so I went to CompUSA and bought a cheap USB 2 enclosure, and now I have myself a very useful external hard drive. Problem is, the thing is loud. For 30 bucks, I didn't expect the enclosure to have any sound dampening. I have the option to put hard drives to sleep checked, but is there a way to decrease the amount of time of inactivity required to sleep the hard drive? Maybe move it down to a minute or 2? thanks.
