How to Add or Remove "Hard disk burst ignore time" in Power Options

information   Information
This tutorial will show you how to add or remove the "Hard disk burst ignore time" setting under Hard disk in the advanced power settings of all power plans for all users in Vista, Windows 7, and Windows 8.

You must be logged in as an administrator to be able to do this tutorial.

Note   Note
Although the disk idle time‑out alone can be configured with the "Turn off hard disk after" setting to favor power savings or performance, some Windows systems might exhibit very small amounts (bursts) of disk activity separated by relatively long amounts of disk idle time. This pattern of disk activity impacts system power savings because the disk is powered up periodically. The disk then remains in the spin-up state for at least the disk idle time‑out, even if the amount of disk activity that caused the disk to spin up is very small.

The disk burst activity time addresses these scenarios by allowing the administrator to configure an amount of disk activity that will be ignored as the power manager accrues disk idle time for the "Turn off hard disk after" setting.

For more detailed information about disk idle detection and disk burst ignore time-out purposes and settings, you could download the Windows Disk Idle Detection Word .doc file from Microsoft.

warning   Warning
The Hard disk burst ignore time setting is only effective if you have the Turn off hard disk after setting set to an amount of minutes and not to Never.

Windows 7 Professional SP1 - x64 [Non-UEFI Boot]

Thanks for that fine tune Power Plan Setting.

It is quite a complicated one to put on. On DC Power i've got only "Minutes" to set, so guess the only choice is 60seconds on a desktop PC.

Hello NoN,

Yeah, but at least you wouldn't want to set the ignore time to be to long anyways.

Yes indeed!

when plugged in or battery powered the Microsoft word.doc mention value to 15-30seconds and 60seconds, that was confusing while reading their stuff!
