I inserted my 2 year old class 4 8GB sandisk card which I used to use with win-mobile treo, but it did not detect the card. So I inserted the card in PC and did a quick format in FAT32, but still same results. In settings->storage, under sd card it says unavailable under total space, but its still clickable, while the mount card is disabled/unclickable. Any help would be highly appreciated. Thanks!!
