I read http://www.techradar.com/us/reviews/audio-visual/televisions/samsung-ue40h6400-1246258/review to get an idea what it does. But HERE'S my guess. These drives must be formatted or prepared for such use before the feature works. Check the manual for what exact steps are needed.

Hi,
My smart TV model is UE48H6400AK.
I am having great difficulty getting Football mode.
Football mode is on
Auto highlights is on, but greyed out.
I have attached a new Samsung M3 hard drive. But nothing seems to be happening.
Am I missing something?
