Memory card corruption? Or something else?
After reviewing my pics from today, I came across these two anomalies. This is the 1st of the anomalies And this is the shot after The rest of the shots were fine, just those two. I do recall during that time the buffer was filling up and I had to wait for the camera to write to the card. Thoughts? I'm using a 5D3 + Sandisk Extreme Ultra 32GB SD card.

Do a complete format of your card on your computer and if you have a wiping software use it. Then format the card in your camera. That should clear the issue.

Kinda . Feb 02 13 11:31 pm Link This is what happened with one of my Sandisk cards. Feb 03 13 12:33 am Link My cpu has been under strain lately on my computer and sometimes I get one third of an image with red and blue streaks like a TV that has lost the station. I have too many images on my computer. Space is becoming a huge problem. I hope the reformatting on the card fixes it for you. Feb 03 13 12:48 am Link Were you shooting Raw? If so every Raw has a Jpeg embedded. Sometimes even if the Raw is corrupted this embedded Jpeg is recoverable and usable. Try searching for and downloading "Instant JPEG from RAW". Run this on your corrupted file (if they are Raw) and you may be able to retrieve a usable Jpeg from them.

Feb 03 13 01:37 am Link On my d70 and on its replacement, a d7000, I have had similar things happen infrequently. The bottom third of the pic will have noise in it. Happened just last week. Formatted the card, all is well again. Feb 03 13 09:53 am Link K E S L E R wrote: I'm assuming you've looked at the image as a thumbnail and in DPP, right? Feb 03 13 01:01 pm Link I had a problem with a card once. After reformatting, I wrote a question mark on the card. I never really trusted that card after that. I love freckles - I hope that you post an image or two of that model. Feb 03 13 01:08 pm Link MC Photo wrote: I viewed them as raw using Lightroom. Feb 03 13 06:17 pm Link Your images appear as if the digital file has corruption. You need to determine where the corruption was introduced into the system. Others have suggested that the problem is with the memory card. This is certainly possible, but is not the only scenario. You may want to try the card in a different card reader on another computer. If you don't have a different reader/computer, try a USB cable directly from the camera to your computer. If that works, then it would suggest that the issue is not with your card, but elsewhere in the process. The problem could be with the card reader, or problems with your hard drive. You may wish to run a disk diagnostic (Disk Utility on the Mac, or equivalent under Windows) to make sure there is no directory corruption on your hard drive.

Feb 03 13 07:41 pm Link Its best to contact sandisk and have them replace the card(s) in question. I had this happen on about 8 CF cards in a eight month period and sandisk replaced the cards for me. Be shure to talk to a live person in their customer service dept. Do it asap! I got the replacement cards in a few days. best of luck, Dave Feb 03 13 07:53 pm Link K E S L E R wrote: Then, yes, it is likely that it is the card.

Feb 03 13 08:33 pm Link I had that happen several times. I was doing some other operation before allowing the camera to completely process the images (jpeg + raw). It was a slow card and I was impatience without realizing it. I eventually got faster cards and now only shoot in jpeg. Doesn't happen anymore.

Feb 03 13 11:47 pm Link Sandisk has a lifetime warranty on "Ultra" products (10 years where "lifetime" is not allowed). Assuming it's not counterfeit - if it happens again - send it away. http://www.sandisk.com/about-sandisk/wa … /#warranty http://www.sandisk.com/about-sandisk/wa … er-guides/ Feb 04 13 07:29 am Link i had similar probs with couple of cards,....started fromating the card 3 times , to be sure the card is empty before the next shoot i would have color shifts , half gray area, etc... so far, seems the multi format seems to work.... i shoot w 7D edit...i always did the single fomrat in the camera, now 3xs or more Feb 04 13 07:38 am Link A corrupted card file is usually caused by photographer shutting off camera while little green light is flashing. Some of the photo file was lost while card was loading. Leave your camera on between shots. And only turn off if the green activity light is off. TOM Feb 04 13 08:38 am Link So I contacted sandisk, they said to reformat and try again, its unfortunate data corruption happens, but just reformat and try again. If it happens again contact them again.
