So the hard drive is in perfect condition and with the traditional beige 1,5m USB 3.0 cable everything works perfectly.
But:
The films have certainly no right 4K resolution. 1080p because it hits more.
5 films with German and English audio track and 3 is consistent with 32 British documentaries.
By contrast, the Dokumetationen have a beautiful, powerful, clear picture, but I deleted most of documentaries,
because it simply does not suit me. Some very rapid succession of different sequences, all of which
are reproduced with perceived 32x. I want to experience the world in peace and not in speed motion.
With others, I think just "boring and poorly chosen" where I vainly waiting for beautiful scenes.
I have kept me only 3 documentaries: Bears, Oregon & The Last Reef.
Otherwise, I have deleted everything and re-occupied. Is therefore used only as a normal external hard drive for backup.
