Question: I have an external hard drive that I only use for storage, I almost never write data to it but it can be useful if I want to access some data that I have in it.

When it s possibile I d like for the hard drive to stay in sleep mode, but Windows Defender wakes it up randomly even if I excluded the drive from the settings. I have now totally disabled Windows Defender, but I d like to keep it running if possible. I m using Windows 8.1 Pro installed a week ago.

How can I stop Windows Defender from accessing the drive?

I m attaching a screenshot of the Process Monitor log, it might help.
