I have several problems actually, but let's start with this one. When I was trying to figure out why my wifi mouse and keyboard periodically quit working, I looked in Event Viewer and found many, many errors of the Event ID 11 category: The driver detected a controller error on \Device\Harddisk1\DR1. The first error date is 6/20/2016. After that they become numerous. Now showing up every few hours.
Can anyone tell me what that means?
