How to Add or Remove "Turn off hard disk after" in Power Options in Windows

information   Information
The "Turn off hard disk after" power option setting lets users set to have hard disks power down after a specified time of inactivity is detected.

When you set to turn off hard disks after idle, there will be a brief delay of a few seconds when you try to access a turned off hard disk as it spins back up and is turned back on automatically as needed. Having your hard disks to be turned off after being idle can help save energy and extend a PC's battery life.

This tutorial will show you how to add or remove the "Turn off hard disk after" setting under Sleep in Power Options for all users in Vista, Windows 7, and Windows 8.

You must be signed in as an administrator to be able to do the steps in this tutorial.

This could be handy if you wanted to set this how you wanted, then remove the setting to prevent other users from being able to change it in Power Options.
