    So, I shot 280,000 shots with my 1D Mark II N, and it died. Just bought a gently used 1D Mark IV. Took it out and shot Saturday. The pictures looked great, but the fast shutter started to lag. Then an error reading on the card.
    Every shot looked great in playback and everything looked fine. Now took the card out and every image is corrupted. The first few are OK, but after that, they all take up space and are the right size, but no program can open them and everything says they are a wrong format or corrupted file.
    Any ideas: Why? How to not have this happen again? How to get my 1000 shots back?
    I am a little hurt and really open to ideas.
    SanDisk Extreme Pro 32GB 95MB/s SD card

    I would try a CF card to see if its the SD card slot problem.

    I have a similar problem with my 1D mark 3, only the CF card slot now, refuses to work. There are no broken pins and I downloaded new software. I have not come up with a solution only to use the SD card slot to record images. There is one possibility, one of my photography student had a similar problem. He tried to print out his photos and had similar results. The machine he loaded his SD card into to print his photos, had a virus on it and this transferred into his SD card.

    I would probably get a new SD card, they can crap out, hopefully its not an issue with the SD slot, but shooting CF and SD is probably a good idea until you know if its the card port or the card.
