A couple weekends ago I was in NY, had taken a bunch of pics when my camera just stopped working. It says memory card requires formatting. At first I did not want to do that because I would lose all the pics. I came back home and took the disk to walmart to try and print the pics out, it didnt work there either. So then I tried to format it but that does not even work. Anything else I can do? Is my SD card dead?
