I just bought a brand new Nikon D3400 and a brand new SanDisk SDXC SD card. When I insert the SD card into the slot it tells me that it cannot read the card and that it might be damaged, but if I insert it into my computer it reads it just fine. I have tried formatting it on my computer and it still doesn't read the card. I have a Lexar 8GB card that works just fine in the camera. Does anyone have any tricks that I can try to make it work?
