I have a gopro camera with a 32gb sd card in it and when i plug my usb card reader into my pc it cant read the card and just says i need to format the card.. (which i dont want to do as there is 6gb of quality footage on it already) windows 7 isnt the problem because my last pc worked with it and that also had windows 7 :/ need help, any replies will be greatly thanked i can give full spec of my custom pc if need be
