First sorry if my English is not very good, but I'm Spanish.
The problem I have with the player is said to have 16 GB and not true, as supported memory card I have introduced a 2GB and says it has 16GB.
Use H2testw and put that memory was 1.4 GB and that he had damaged disk sectors, by ChkFlsh 1.10 changed the 16GB size to 1.4 GB, then put music and videos and when he got to play me formatting error, delete all files and got only one and if it worked, I understand that happens to the player.
The chip is a rk2705 Rockchip,
and the memory chip is a Hynix: h27uag8t2mtr bc 933H
the brand of player is rizona, I put the eBay site that you may know as the player.
