Win7 dual hard drives frequently emit sound

If you do not read from the disk for a period of time, Windows 7 automatically shuts down the hard drive by default and then restarts it the next time you need to read and write. Therefore, it is not surprising to hear the sound of the hard drive turning.

Although frequent shutdown startup does not cause much damage to your hard disk's life, you can choose to turn this feature off if you need a quiet working environment. The specific actions are as follows:

In the Start menu, open the Control Panel. Enter the hardware and sound-> Power Options window in turn.

Select the current power plan you are using, and click the Change Schedule settings link to the right.

Select "Change advanced Power settings" after entering the Edit Schedule Settings window.

Expand the hard drive-> turn off the hard drive after this time. We can see that the default setting is to turn off the hard drive after 20 minutes. You can reset it as needed, or simply set it to never, and click OK to save the entry.
