Took about 30 photos with Canon 5D2 tonight, put the 16GB Sandisk Ultra card in the reader and it didn’t auto-mount. Removed it, it mounted as empty volume. Put it in the camera, it came up empty. Put it back in the PC, it mounted with standard camera directory structure (DCIM and MISC) but no image files. Ran Recuva to look at erased images, found plenty of old photos and videos but nothing at all from earlier today. The same camera was successfully used earlier in the day (with another card). I’ve not had problems with this card before. I am very puzzled by the absence of any trace of the afternoon photo shoot.
Any suggestions on recovering the image files? More importantly, any ideas on what caused this and how to avoid it in the future?
