    I have annoying problem with windows 10, all my loud non OS hard drives never sleep because explorer.exe is accessing them exactly every 10 minutes and querying them for free space.
    I used Process monitor to verify this.

    Its a clean install of windows 10 I haven't even installed anything yet. Any ideas how to stop it?

    You can always try, go to run- service.msc, then go to windows search RT click properties - stop, disable, and see if it helps, stops file indexing. Also stop defender from Real time protection of these drives.

    Also check disk properties to see if ready boost is enabled.

    damn and with Win8/8.1 we couldn't keep them awake! Now they wont sleep for those who want them too. It's never ending, even the fixes MS offered where little help.

    @oldiebugs1 nice idea, good luck OP

    Funny, usually everyone doesn't want them to spin down.

    I figured it out

    Windows had assigned a drive letter to a RAW partition. I removed the drive letter and now even though explorer still queries the other NTFS partitions every 10 minutes, the drive doesn't need to spin up in response.
