    Doesn't the disk spin down when you are not using it?

    Just go to Energy Saver In System Prefs, and click the check box for "Put the hard disk(s) to sleep when possible"

    It should spin down my FW drive does spindownHD tells you if it has spun down if you can't tell. Its in the developers tool kit.

    quick question

    Hi guys, just a quick question: whenever I try to modify something on system preferences -> energy saver (something like the "automatically reduce the brightenss of the disbplay before sleep") my changes go back t the original defaults and tu a "custom" energy mode. Is there any option I have to uncheck to make sure I can customize everything and keep it as I want it? thx!!

    I believe this behavior is by design. When you change some setting in Energy Saver, it lists your settings as custom. However, it shouldn't be reverting to the defaults - are you clicking Apply Now if the option to do so is available? If it isn't, closing System Preferences should be sufficient to apply the new settings.

    Even if only the 'Books are mentioned, it may seem like at least some iMacs are affected, too...
