Strange memory card behavior
I went out this afternoon to a local lake to practice my BIF and hand holding techniques on some friendly gulls. I took about 200 images with my 1DX using a Lexar Professional 800x 16GB card which I have used many times before. The card had a few images on it already. I was able to view and delete images as I was taking them (to get rid of the out of focus ones). I had the camera set to RAW and only had one card in the camera. When I returned home I took the card and plugged into a Delkin Devices reader and my MacBook Pro. To my surprise neither ACR or Photoshop will open the images. I get a message that this file type is not supported. They appear as CR2 files but will not open. Also I put the card back in the camera and it will not display the images either. Shocking since I had just looked through them in the camera 15 minutes earlier. The images that were on the card from an earlier shoot are still there and can be viewed normally.
I would love to know what happened here and can I recover my images?

Hi Joel,
It's hard to tell what happened, but it is possible the blocks were new files were written to lost data. Try rescue pro to see if it helps. Also try to simply copy files as opposed to downloading with Adobe.

Hope you can figure it out. If you can't, I would send the card back to Lexar. I've sent a card in before - one that wouldn't format - and they sent me a new one within a couple of weeks. No questions asked.

I thought of posting that link to my experience here, but it sounded a little different in your case. Hope the same fix works for you. I have not had a single frame recur with with the issue in thousands shot on that card over many sessions. The format fixed it and the new card reader prevented it from happening again.
