Please go back to the first page of this thread and read the earlier replies... "Pink" images are truncated JPG files. (Even when shooting RAW, the playback on the camera and thumbnails or previews on your computer are actually JPGs embedded within the CR2/RAW file.) The possible causes and solutions are still the same:
If the corrupted files are appearing on the camera's LCD screen...:
1. Memory card... do you regularly format it in camera? If not, that can cause problems. If so, good, but it might be failing. Try a different card. (Note: Be sure
2. "Rebooting" the camera might clear some faulity instructions "stuck" in the camera's circuitry. See posts on 1st page how to reboot a 5DII.
3. Camera firmware can become corrupted, too. A reinstall might fix that. Download the latest firmware for the camera from the Canon website and install it (Note: follow the instructions there carefully and be sure camera battery is charged up, so that it doesn't shut down midway through the update. Also be careful not to touch any of the camera controls or turn it off during the update. Stopping a firmware update mid-stream can "brick" a camera, requiring it be sent in for service.)
If your images look fine on the camera, but are appearing corrupted on your computer, it can be any of the above, or....
4. Card readers are recommended to download images, but can fail for several reasons. Have you changed anything in your computer? Updated software? Connected a card reader differently? If you have made any changes, try undoing them and see if that solves the problem. Also might need to reinstall the card reader driver (software within the OS that works with the reader) or install a new one if you've updated your operating system. Troubleshoot by using a different, known good card reader or try downloading by directly connecting your camera via the USB cord that was supplied with it. If either of these those work okay, replace the first card reader.
5. If you regularly download using the USB cord supplied with the camera, that cord might go bad or it's plugs or the sockets it connects to at either end might become worn or damaged. Try using a card reader instead, and see if that solves the problem. (This is one reason it's generally better to use a card reader, instead of this cord.... If the mini-USB socket on the camera gets damaged, it would likely be a very expensive repair. Also, card readers can be faster downloading, than the cord. Plus the camera's battery is drained during downloads when the cord is used.)
Canon DSLRs don't use a CCD type sensor. They use a CMOS. It could be the fault, but also other components such as the analog to digital converter, memory card socket, things associated with image playback and more can be at fault. It'spretty impossible to say, would only be a wild-a** guess for us to try to diagnose the problem and identify faulty parts via forum posts. So, do some trouble shooting, as described earlier and above, and see if that helps you figure it out. All the above you can try yourself at little or no cost and might help you identify and/or solve the problem. If they don't, then it's probably necessary to seek professional help through Canon's service dept. or an independent repairer.
