I boughed an full HD camcorderAiptek and this SD card was recommmended. When I insert it I get "card error" so I tried it in my Pentax camera and I got he same message error. I took the SD card (not same model) wwhich was in my camera and inserted it in the Aiptek and it worked properly. So I asked for a replacment shdc car which I recived today and i have the same "card error" message.
So, I guess the problem remained with this type of 6gb card ???
