Business Week Online of all places discusses the ways in which you can rescue digital photos that you think are lost from your memory cards. Touch wood, I’ve never actually experienced losing photos due to a faulty card, but if you have this article recommends several software packages that may help you to recover your images:

“I loaded three of the programs—RescuePRO, Image Rescue, and ImageRecall—onto my computer and used them to recover my pictures from a CompactFlash card. I was unable to deliberately damage the card, but I “lost” individual images by opening the card access door on my camera while it was still writing the image and index data to the card. Neither the camera nor my computer could see the pictures, but all three programs could find them and write them to the computer’s hard drive. I also reformatted the card: The software still found pictures, including a hundred or so that I’d deleted months ago.”
