This was a 32gb card which had about 8-10gb left. After reinserting the card, the error message changed to "Cannot Create File Folder" and upon plugging in the card to a computer via two different sources there were no photos showing. Is there any way to recover my photos? I've found a lot about this issue, but nothing about it occurring while actually taking shots. Thanks!
