I have a Canon EOS 50D camere, and yesterday I bought a San Disk Extreme Pro 32GB memorycard. Took 5 pictures, before I got an errormessage telling me to switch card. Removed the card, and inserted it again. Then I got the message that I had to format the card. Started the formating, but then the message “can not format. switch card” appered. Tried several times with no luck. When I connect the camera to my computer, the computer finds the camera, but says that there are no pictures on it. When my brother puts the memorycard in his Nikon camera, all the pictures are there. He tried formating the card in his camera, but it won’t format there either… Iv’e checked that the card is compatibel with my camera.
Does anyone know what is wrong, or what I can do to fix it? Could it be the card that is defect???
