I know there is a sticky on here, but want to make sure that that is what I am looking at:
Two days ago I shot a bunch of photos in a cave. Immediately before leaving the cave I reviewed the photos on the camera. An hour and half later when I put the SD card in the computer over a hundred photos were missing from my SD card starting on IMG_9448 and running to IMG_9999. IMG_0001 to IMG_0040 (which were in a second folder) were still there.
I immediately moved the existing photos off the SD card only to see this. Apparently even though there are *no visible files* in all the folder on the card there is still 8.1GB of data on it. Which happens to equate the amount of photos and videos I am missing. The camera also shows this amount of data on the card and multiple computers say the same. These photos are *really* important to me and I need to get them back.
