<p>I have a brand new D3200 that was fine for the first few days then the "cannot display file" and "memory card damaged" message started appearing.<br>
Also, after turning the camera on and taking the first photo the little green memory card light would stay on for almost a minute which would hang up the camera.<br>
Removing and reinserting the memory card seemed to clear the problem temporarily. It would come back.<br>
My experience with computers led me to the tiny gold fingers on the memory card.<br>
I removed the card and used an eraser tip (mildly abrasive) on each finger to burnish the contacts. I shaved the eraser tip with a razor blade to fit it fingers.<br>
Since doing that, the camera has been OK.<br>
