Shot almost a whole card today and went home to download it. Camera suddenly said "No Images" Card reader said, "card is not formatted!" Oh CRAP!!!! So I found http://www.z-a-recovery.com/digital-image-recovery.htm It recovered all the shots, plus some from an old shoot. And it is completely free. I think I read in the FAQ that it is only free for 4 folders. Not sure if that is 4 at a time, or 4 lifetime. Anyway, the only drawback is it renames the extensions to .tif I downloaded and installed http://download.cnet.com/Extension-Changer/3000-2072_4-10394272.html Extension Changer which worked like a dream. Just drag the whole folder onto the Extension Changer interface and it does the work for you! This is the first time I have had to recover images and it was pretty painless. Now I have to decide what to do with the card. I reformatted in camera, shot a bunch of tests, and it works fine. Have no idea what happened.
Hard to say what happened. I have a card (Xd) that started doing odd things after a few months. I did not lose the photos. But it would not allow any software to delete after downloading. The only thing I could do, was format it. Which would be OK for one session. The next time, back to it's old tricks. Repeated this process a few times, and gave up. By then, prices had dropped, so I bought a new one of much greater capacity. Boxcab E50
It not only change the extension but change the file format also. Not 100% on this but I believe that a TIF takes a more space then a JPG or JEPG, something like 10X. Gary
Actually, I should have given more information. I do not shoot in JPEG mode. I shoot in raw Nikon NEF. If I had shot in jpeg, it would not have changed the extension. It didn't physically make any changes to the file, it simply gave it the wrong extension. I changed the extensions to NEF and then Photoshop was able to read the files as Nikon Raw. Otherwise it would have told me that it was a corrupt TIF file, trying to open it as a TIF. Hope that explains it. I copied my OP from one I made on the Nikon forum, so I left out some stuff that Nikon people already know. Should have edited it for this forum.
