    How to Add or Remove 'Turn off hard disk after' from Power Options in Windows 10

    The Turn off hard disk after setting in Power Options lets users set to have hard disks (HDD) power down after a specified time of HDD inactivity is detected. This setting will not affect a SSD (Solid State Drive) or NVMe.

    Having your HDDs automatically turned off after being idle can help save energy and extend a PC's battery life.

    When you or anything tries to access a HDD that has been turned off, there will be a delay of a few seconds as the HDD automatically spins back up and is turned back on before being able to access it.

    This tutorial will show you how to add or remove the Turn off hard disk after setting under Hard disk in Power Options for all users in Windows 7, Windows 8, and Windows 10.

    You must be signed in as an administrator to be able to add or remove this setting in Power Options.

    @Brink Does this affect external hard-drives or do those often have their own internal power management system? My desktop only contains SSDs internally but I often have external hard-drives connected from time to time and may be away from my desk for some time.

    Hello @KabyBlue,

    Yes, it will also affect external drives. However, their own power management will also be a factor.

    What would u recommend setting it too for external hard-drives (non SSD types)?

    It should be set to a time that best fits your usage. You would want a time that is not too short to prevent the drive from having to power up (spin up) often, but not too long to save energy and wear and tear when not needed.

    I'd say figure out an average of how often you access the drive, and add a bit of time to that to use. You can then adjust the time to add more as needed if you find it still having to spin up often.
