    HD sleeps, not supposed to...?
    After my screen saver and computer sleep goes on for the amount of time i set in the energy saver prefs, the whole hard drive sleeps. however i didnt click the box thats says "put HDs to sleep when possible". why is it doing this even though i didnt tell it to?

    Well, why would the harddrive be left on if the computer is asleep?

    It would just increase the wear and tear on the harddrive and have 0 advantage.

    The checkbox is there to help save energy, i.e.let's say you are currently reading a document and the harddrive is not currently being accessed, then the harddrive can be stopped, thus saving battery life.

    If you prefer a slightly faster system, the harddrive will not stop spinning whilst the system is on, giving you a slight speed advantage.

    Btw, it would be a bad idea to leave the harddrive spinning whilst transporting a laptop, so that's another reason why it automatically stops.
