I brought two 16gb pro duo off ebay. I know that it might not the REAL and it's just an knock off, but how could i tell. Ok to the question.

I formatted it and put iso games in it, but it only show the frist game the rest are all corrupted data. Yes, it's in the right folder and it's CFW 5.00 M33-6. When i try to start the game it load up to the sony logo and it takes forever to load, yet after waiting forever it shows nothing. Try reformatting a hundred times and no good.

I try my 8gb and everything is fine. What am i doing wrong here.
