I have a 2gb sd card and a 8gb hcsd external card for my fuze 4gb. The 2gb card works, but the 8gb doesnt, when i plug my mp3 to the computer it detects the card but it says that theres 0gb on it, not that its full but that theres no space on it. I tried it with my computer or camera and it works, they detect 8gb. Only that stupid fuze can’t detect 8gb. Can anyone help ?!?!
