None 4 months ago - have all problems?

Have already herewith my third hard drive bought (Intenso 250GB, 500GB Toshiba, Verbatim 320GB) to attach it to my Samsung UE32ES5700. The first two were no longer detected within 30 days from the television and therefore declined. Unless you formatted everything. Thus it is only once again, but all shots singing away. So even with this product. Once in the first week, the panel was not recognized, and I had to reformat. Was fortunately not much on it. Then the plate was wonderful for almost 4 months. Now suddenly realized the Samsung disk no longer. When I return everything reformat it will indeed go but all the pictures are gone. That can not be the intention of the manufacturer? Whether I still can not return? What then do I buy? Useless as a recording medium for this Samsung TV.

Additional in February 2014:
In the meantime, I've made an update to the Samsung TV. Behold, my bad-reviewed disk ran again. Til today. When you delete a recording they failed their service. She turned the television on and after one minute on and off again and again, etc. TV was only possible with removed panel. Collected and formatted on PC. Again attached to the USB port on the Samsung and the prompt followed by television format. Everything worked. The drive runs again quite well. Lightweight running noise can no longer be heard in the distance of 2 m, especially since the TV would always outvote the plate.
I am happy that everything is back on track and increasing to 3 *, because really was the old firmware of Samsung blame. The unit is now in order, except for the temporary problems deleting (?). So it's useful !.
