My SD card was OK... but the CF pins were bent inside the camera.....I manufactured my own tool from a small round skewer, like you use for Olives in a Martini... I was able to straighten the pin(s) and then I also had to fix the female slots in the Card(s) by reaming them out and removing any anomalies that might catch and bend the pins again. So far so good. Be very careful with the pins.. if you snap on off... then I suggest sending the camera to authorized Nikon repair facility.
