So I have a slight problem. One of my CF cards appears to be corrupted in some way. Now there aren't any pictures stuck on it or anything, it somehow happened after I transferred the last batch of pictures, but now the card will not format. Does anyone have an idea of how to get it working again? It's a SanDisk Extreme III 8GB if that helps. I have two more so it's admittedly not really hurting my workflow that much but I'd still like to get it up and running again if I can.
