I have a Canon 60D. I was shooting and had about 200 pictures when my camera said that my card was full. This didn't make sense because my card held 16GB. When I tried to look at my pictures through my camera, it suddenly said that there were no pictures on the card. I inserted the card into my computer and the pictures weren't showing up either. However, when I look at the logistics of the card, it says there is about 1GB (or so) being used up. So, I know that the pictures are on there, but don't know where. Any ideas?
