Ok so I have a number of files and channels on my SD card but if I insert it into the wii some of the files randomly disappear and I have to recopy them onto the SD card. However I realized that this only happens when a certain amount of files are on the card. The card is a 16 gig micro sd however because of this problem I can only have a couple megabytes of data on the sd card. Can anyone tell me if this is a problem with the sd card or is it a possibility that it could be a problem with my wii? I would try to test another sd card however I only have one and that is why I came here.
