I've been using SD memory cards since they first came out and for more than just photography. Frankly, I had heard of failures, but considered these cards to be nearly bullet proof since I had never had a problem. That all changed last weekend after coming home from a local event and finding out that I could not read or write from one of the two cards in my Pentax K3. Thankfully, the K3 has the dual card system and the other card was fine, but I had no idea that there was any sort of problem while shooting and there were several shots that I considered to be rather important from this shoot.

Anyway, my reason for posting this is to point out how important that second slot can be as a backup, as I would have been really upset if I had lost the photos from this shoot. It really makes me wonder why any manufacturer would bring out a new camera body or system without a dual slot available. I personally will never own another one without the backup slot, lesson learned! By the way, the defective SD card appears to format normally, but will not otherwise read or write in either my camera or on my computer system and I have no idea what might have caused this failure. Good luck and good shooting to all.

Please excuse my reading skills if I missed it. What was the Brand and size of the SD card in question? My computer training leads me to agree with the person who noted there are ways to recover data off bad disk. Cards and drives are cheap so no one bothers to recreate what was lost except the trash divers. Price is the driver and recovery is not cheap.

Thanks for sharing your situation. It has me thinking about how my camera works when I look at the 9 little pictures on the back of my camera screen and scroll back thru say 27 photos. Is it getting the info off my card or internal memory of camera. Is there a way to check data on just backup card number 2?
