I use my computer to record Broadcast TV show everyday. That man I have to leave it on all the time. With Win 7's power management, it goes to sleep after a few minute of inactivities. But my External Hard Drive stay on all the time. Is there any way I could set to make my External Hard Drive goes to sleep at the same time as my computer does?(My External Hard Drive is home made, that mean I bought an enclosure and add a hard drive in with USB/eSATA connection). I have another computer that have a 2TB Seagate External Hard Drive that come with the software that would goes to sleep when the computer idle.
