Windows 7 cancels the hard drive automatically off

                  The number of friends who use dual hard drives is more and more. Generally, one of them is used as the system master and the other is used as the slave to store files. If you are using Windows 7, you will often hear the sound of the hard disk stopping and starting. For example, when you turn off the computer, the system will automatically start the slave disk (if it was stopped before).
In fact, this is the hard disk auto-saving function provided by Windows 7. By default, if the slave does not read or write for a period of time, Windows 7 will automatically shut down the hard disk, and start the slave again when there is a read or write operation. . Such frequent shutdowns do not cause too much damage to the life of the hard disk, but the sound of starting and stopping is not very comfortable.
We can easily turn off this trick. From the control panel, go to the hardware and sound rarr; power option window, select the current power plan, click the change plan setting button on the middle side, enter the edit plan settings window, select to change the advanced power settings, expand the hard disk, you can see the default The setting is to turn off the hard disk after 20 minutes, we can reset it, or simply set it to never, after confirmation, it will take effect.
Of course, if you are using Vista, you can do the same.
