I had this happen some years ago with a D70. It was one single pin at the end of a row that was bent and I managed to straighten it using a pair of my wife's tweezers (the flat ended type). I didn't enjoy the experience, or the thought of the repair bill if I got it wrong. Since that time I've used just a single CF card, currently 16GB with my D700, which gives me space for approx. 600 14-bit lossless compressed RAW files and which I almost never remove from the camera. I used to carry a battery powered back-up 80GB hard drive and connect the camera to it but now I download the RAW files from the camera to an iPad - this has the added advantage of being able to view the images at a decent size, a great help when deciding what to keep and what to delete.
