Question

I have a Kodak easy share # Z710 and I can't all of a sudden can't delete the pictures on the memory card.My camera says that the memory card requires formatting.Can you explain to me just how to do this, since I sure can't find any directions in the manual. I've had the camera for almost a year and this is the first time thishas happened? Does this mean my memory card is shot?Please inform...............Jeff
