Teach you how to turn off the sound of the small 7 system frequently reading the disk

Many users report that the hard disk often sends out the sound of stopping and starting, I don't know what is going on. Many computers are equipped with dual hard disks, and one of them is usually used as the system master and the other is stored as a disk. In fact, this is the automatic energy-saving function of the hard disk that comes with windows7 (not to promote energy-saving and environmental protection? Xiaoqi will not fall behind people~@). If you do not read or write to the slave disk for a period of time, Windows 7 will automatically shut down the hard disk by default, and then restart it the next time you need to read and write. Therefore, it is not surprising to hear the sound of the hard disk turning.

despite frequent closures will not have to start the hard life bring too much harm, if you need a quiet environment, you can also choose to turn this feature off. Specific operation is as follows:

1. In the Start menu, open the control panel.

2. turn into the "Hardware and Sound - & gt; Power Options" window.
