I spent about an hour taking some photos this morning. Periodically, I would review a picture to see if it was light enough, in focus, etc. I finish and plug the ol' SD card into my laptop and NOTHING is there. I grab the camera and reinsert the SD card, click review, and there are all of my pictures. Oh man was I livid.... However, my new lease on life directed me to intelligently solve the problem, rather than beat the SD into fragments with a 3 lb. maul. I found a free program called "Zero Assumption Recovery" that can grab corrupt files off of SD cards and save them to a folder of your choosing. Now, it did take 17 minutes, but to get all of my pictures back.... I'll sacrifice instant gratification for solid results. I found the program by Google-fu and wanted to share.
