I have been searching this forum for a couple days now trying to find a post I read about a bug in the disk writer that causes your memory card to show 0mb of free space on your sd card. I can write all of my roms just fine to the sd card but when I close the writer and open it again only 3 or 4 games will be there and it will say I have 0mb of free space. I have tried 4 different as cards. 2 of them are Samsung sdhc class 10 32gb, one Fuji film class 10 32gb and one Samsung 8gb card but I am pretty sure the last one was fake. The post that I read in the thread u can't find said there are some games that caused this. One of them being Tetris. Is anyone else having this problem? Is there a list of games that may cause this?
