History: I took a lot of shots with my Canon 7D and filled the CF card yesterday. I deleted what I didn't want and continued to shoot without filling the card. When I got home, I reviewed the images in the camera and deleted more that I didn't want because they were either redundant or out of focus. When I was ready to upload to the computer (MacBook 2014), I put the CF card in a "Sunpak" card reader and plugged into a USB port before following my usual steps which were: open Elements 13 Organizer, click "Import", click "from Camera or Card Reader." At this point, I kept getting <None Detected> no device found. I plugged the card reader into the other USB port and followed the same steps and got the same result. As an alternative, I put the card back in the camera and plugged the camera in with the USB cable. I still wasn't able to use the Elements 13 download, but the connection started working in another window that showed the computer was processing in excess of 33,000 images! I doubted neither the CF card nor the computer disk has room for that many, so I pushed "stop" to close down the import (or whatever it was doing) in that section. The new photos weren't included in that operation as far as I know, and none of the old photos that came through before I stopped the process appeared to be on the computer unless they're double images in the photo section.

The main problem: The CF card no longer has any images on it. I didn't think I told the computer to delete anything (I usually do that in the camera by reformatting when I'm sure everything has transferred to the computer). Obviously I did something horribly wrong.

Any ideas what I did to delete the card? Did closing the download by hitting "stop" erase the card? Would it be possible to find the images that seem to be lost or are they truly gone forever? If the images are to be found, where should I look (I believe I've looked at all of the files on the computer). I should mention that the computer iPhone and tablet are linked to some degree and appear to trade photos. The shots I took yesterday are not on the other devices.

Sorry your having trouble, I had a CF card fail about 10 yrs ago, did the recovery route, took a bit under 4 hrs for the recovery and another 8-10 hrs sorting the recovered files and it was only a 2gb card.I couldn't even begin to tell you how many file were recovered, but the card had been formatted in camera after every down load.

Thanks for taking time to reply to this post everyone. It was a relief to learn it might be possible to retrieve lost images from the CF card. I looked at the sites mentioned in your responses as well as calling a local camera shop for advice.

For Richard: I did put the card back in the camera to check for photos. The "No Image" message came up each time I tried it. The cable I ended up trying to use was still in its original packaging and should have been trouble free, but it was after using it that the images disappeared.

My final approach was to take it to the camera shop since I didn't want to risk making a mistake. If I'd only had my usual assortment of random photos on the card, I might have been tempted to try to fix it. Everything on the card was from a Pet Portrait fundraiser, RAW files shot yesterday. People had paid in advance for photos which, so far, I'm not able to provide. I hope the camera shop comes through. They quoted $70 to do the repair until they noticed that the card has free manufacturer repair warranty. At this point, there was nothing to lose by going that route, and I have learned that there are recovery systems out there for all kinds of technical issues.

Thanks again for the great advice. I should know Friday or Saturday whether I'll have photos to edit. Keep your fingers crossed.
