While it should work there are too many other issues such as USB 3.0 drives that seem to cause this issue. There's also the matter of the formatting. Try it in a format noted in the product manual and from what I've seen, forget USB 3.0 drives for the time being.
I have samsung 40"EH5330 smart led tv .
I want to know does it support 1TB portable HDD
My 250GB HDD works fine on it
If not then what is the maximum size HDD it supports
