D800, and a Delkin Black. I complained to Delkin. They are sending me a 
reader, and requested that I test the card with that reader. The shot 
you see is a ten shot multiple exposure. I was testing to see how much 
time was needed between shots, to get a similar effect to a long 
exposure. despite the corruption, my conclusion is that it can be done. 
In a calm bay it takes about 2.5 seconds between each shot, for a ten 
shot exposure.
