Corrupt Compact Flash Card????
I use a SanDisk Extreme Pro, 90MB/s, UDMA7, 16GB compact Flash card in my Canon 5D MKlll camera set to record camera raw images. Recently, I shot many images while away on vacation and was able to view all the images I took via my camera's play back method. After returning home, I tried to download the images for processing in Photoshop Bridge and the download stopped before downloading all the images. I retried several times, but with the same result. I'm puzzled that I can play back in the camera all images just fine, but cannot download all of them onto my computer.
Does anyone have any suggestions? Also, does anyone know of a company that might be able to retrieve all the images so they can be downloaded into my computer.
The second card that I have installed in my camera was set to record in jpeg, however, I prefer to process my photo's for printing in camera raw for all the reasons most of you already know. Fortunately, I am able to download all the photos from the second card in my camera, however, they're not what I prefer to process with.
Just to double check a few subtle issues:
1) You've described card 1 as the target for RAW. During the playback, is '1' displayed in the upper right corner as the source for the images being displayed?
2) What software are you using to download? If you connect a USB from the camera to the computer and navigate to the CF card via the computer's OS, do you see the CR2 files? Can you copy them that way?

Are you using a card reader to download the photos to the PC? If so, can you download successfully directly from camera to computer? Sometimes, a bent pin in a card reader is the source of file transfer problems.

Thank you for your help. I found a source for Sandisk data recovery on the internet and it appears that I have a corrupt disk. On the playback, the camera is set to playback disk 2 and that's why all of the images were playing back in the camera as playback is set for card #2. I can send the disk into the recovery company but they charge more than I'm willing to pay for their service.
Regarding your above comment "is '1' being displayed in the upper right corner", I don't know what right corner you are referring too.

The 1 or 2 in the upper right corner tells you the source card number being displayed. See explanation & diagram on page 252 of your manual. Given you have the corresponding JPEGs, I'd hesitate to spend any money on a card recovery before being very thorough in confirming the card is the actual problem. I'd also always confirm the camera display is set to card 1. After removing and replacing the CF card, always take a moment to specifically review this icon and reset the display, if needed.
What happens when you change the display to card 1 via the camera menus? See page the Set-up menu and / or page 120. Does the camera think there are any images on the card?
Of course any technology can fail, but CF cards are pretty far down the list of common / possible causes. For example, what happened when you connected the camera to the computer via the USB and navigated to the CF card? Can the computer OS see the card? Can you see the contents of the card? Are there CR2 files on the card?
The EOS 5DIII won't capture images if it can't write images
as configured via the menus. If you've configured the camera to write RAW to 1 and JPEG to 2 and the camera cannot write files in these formats to the two cards,
it won't write at all. Is the camera configuration exactly as you've described? Pages 117-122 show the applicable menus to confirm the configuration you've described. The LCD in the top of the camera also tells you the card configuration. See pages 21-22 of your manual for details.
If the camera will record and playback images on card 1, you should be able to download them. If you insert another CF card, what happens when you capture a few images?

Thank you very much for your detailed answer to my question. I will follow up on your suggestions shortly. I'm in the middle of a project right now, so I will have to review the details of your message as soon as I'm through with my project. Thanks again.
Exactly how are you downloading the images to your computer?
Are you removing the card from the camera and using a card reader or are you downloading from the camera via a USB cable?
Are you using some app to download, or simply using your computer's operating system to copy the files onto it?
Do you regularly format your cards in-camera?
It's rare for a card that's worked in the past to suddently "become corrupt". Memory cards are solid state, so there isn't much to "go bad".
Most likely is a problem with connectivity between card reader and computer or between camera and computer (depending upon what method you're using). Have you changed anything lately? Using a different card reader or have it connected to computer differently, for example.
It also could be a failed USB cable, if tethering the camera to the computer to do the download. Or it could be a bad USB socket (on camera or on the computer).
If you were moving the images off the card while still in the camera and the battery was low and the camera had to shut down, the interruption could corrupt the files. (One reason not to download from camera, but to instead use a card reader. It also lessens the risk of damage to the USB socket of the camera, which is likely to be expensive to repair because most are part of the camera's main board... replacing a memory card socket is usually less expensive: easier to get to, less labor, and it's a modular sub-assembly on most cameras, so replacement parts would be cheaper, too. It's also a good idea to copy images off the card, rather than move them. That leaves the originals in place on the card, in case there's any problem with the download.)
As mentioned in a previous response, it also could be a damaged memory card socket in your camera. Remove the memory card and inspect the pins at the bottom of the socket. Also look closely at the connection end of the memory card itself... for any sign of damage or a broken pin stuck in it.
You should work through each of these possibilities... substituting a different card reader, using USB cord instead or substituting a different one, etc.... testing each in turn to rule out the various possibilities and try to identify the source of the problem.
If you know the image number where the download stops, then just highlight all of the images before that corrupt image. Then you can start a second download by highlighting all of the images right after the corrupted image(s) and that way you will only lose the corrupted image(s). One other thing. ALWAYS reformat the card in your camera, NEVER using the computer. I have used San Disk Extreme cards my entire digital life. I have accidentally run them through the washing machine and the dryer and they still work perfectly. I have one 64GB card that I not only washed and dried, but it has a dent in it thanks to an angry bull (I used to shoot rodeos from inside the arena) and it still works, too. I have always reformatted in camera. To say that I am not kind to my storage cards would be an understatement.
If you can read the CF Card in camera, than download the photo's from the camera on your computer via the connection of USB port. Re-format the CF Card in the camera you will be using and it should be fine!
Isn't it nice having two card slots? : )
YES! ALWAYS reformat the card in your camera, NEVER using the computer.
SanDisk are the best CARDS! I have used some Lexar.

Does the download stop on the same photo each time? If so try again from the next photo after that one. If that works it's only a single corrupt file and you will have saved the rest.
stumbo, the answer to your first question is that your camera does not display your RAW images only the jpeg equivalent. Second I believe Sandisk still offers free recovery software for their flash cards, so check that out before you spend money, good luck.
Two things that I would try:
1. Download the raw files directly from the camera to the computer. This saved my butt a couple of times.
2. Sandisk makes recovery software got their cards. It's about $50. I have used it a couple of times to recover images from SanDisk compact flash cards. What a life savior.
Best of Luck!
