Cyber-shot DSC-F828 memory stick error C:13:01

HI,

Please clean the gold contacts of your memory card.Take any lead pencil. Take the eraser and rub it on the gold contacts on the memory stick as if you are erasing writing on paper. Do this for about 30 seconds or more until you get all the gold contacts. Put the stick in the camera, switch to 'Setup', then turn the camera on. The 'C:13:01' error will automatically disappear. At this point, quickly format the memory stick using the camera's format feature.NOTE:
Al;ways use the camera's built in function to format your memory card.Do not use the computer to format the memory card.

If you still face any problems then you will have to get it repaired.

Thank you
