Hi, I have a PleoMax (Samsung) 256GB SD memory card. It is supposed to be a "high speed" card (10MB/s). It works fine on my PC but my Wii console doesn't seem to be able to read it. I get a "This card is not usable." message whenever I try to use the card in the Photo Channel. Do the files in the card have to be in a particular layout or directory structure? All I have in the card is a few JPEG pictures from a Cannon Powershot digital camera. Thanks in advance! Anot PS. The web browsing channel is really cool!
