With the rapid decline in the price of hard disk, the use of dual-drive friends is more and more, is generally a piece of the system as the main disk, the other as a storage file from the disk. If you are using Windows7, you will often hear the hard drive stop and start sound, for example, when the computer is turned off, the system will automatically start from the disk (if previously stopped).
In fact, this is the Windows7 provided by the hard disk automatic energy-saving function, the default settings, if a period of time from the disk does not read and write, then Windows7 will automatically close this hard drive, there is read and write operation to start again from the disk. So frequent shutdown startup, although not to the hard drive life will cause too much damage, but the start, stop the sound is not very comfortable ...
We can conveniently close this "awkward" feature. From the Control Panel, enter the hardware and sound → power Options window in turn. Select the power plan currently in use, the Change Schedule Settings button on the single hit side, go to the Edit Schedule Settings window, select Change advanced power settings, expand hard disk, and see that the default setting is to turn off the hard drive after 20 minutes. We can reset it, or simply set it to "never," and confirm that it will take effect.
Of course, if you're using Vista, you can do it the same way.
