Strange glitch/image errors with 6D

[kamerakind]

It's the second time within 2 weeks that one of my 6D's spits out something like you see above. Anybody ever saw this and have an idea what to do? Probably the sd card have a problem? Is my sensor about to die? Any help is appreciated. Thanks folks!

I would certainly suspect the SD card first.  Do you have more than one?  If it happens on multiple cards of course it suggests another problem may be the culprit. 

Try doing a full reformat of the card (after your photos are all uploaded somewhere, as reformatting will delete them).

Yes, I have 8 SD cards. All from one manufacturer, which makes it hard to "recreate" that error. They get reformated before every job I do so that not might fix it. Maybe I'll sort that one out which had the above image on it and will see whether the error recurrs.

When you format the cards be sure you do a low level format, and not just a quick format.

"Maybe I'll sort that one out which had the above image on it and will see whether the error recurrs."

Maybe?    Scott is correct.  You need to get rid of the bad card.  There is no, "maybe"!

So assuming your camera doesn't have a menu option that says "Randomly corrupt my images?" and it's set to "Yes" I'm guessing that you have a flakey memory card.

Do you number (or somehow identify uniquely) each of your cards?  In other words... is it possible to determine if this keeps happening with the same one card or does it randly occur with any card?

There are several good brands for cards, but you'd want to make sure you have a genuine card and not a counterfeit (they're out there).  To avoid getting a counterfeit, you'd want to make sure you buy cards from authorized dealers.

TTMartin pointed out that when do format the cards, check the "Low Level" box.  That should perform a "write" to each block on the card and verify that the write & readback succeeds without error and it will mark bad blocks if it encounters them.

Hi kamerakind, I have the same problem! Do you already found a solution? And my 6d shows me a message on the screen saying "Cannot playback image" and that image in the computer looks like yours. And when this occurs the camera freezes.

Strangely, the previews of the corrupted images are fine on my 6d. I formated my sd-cards on low level like the other users recommended and up to this day, don't saw this error again. so maybe it really has to do with bad/corrupted/fragmented sd-cards.

The fact that the images don't appear corrupted in the camera doesn't tell you much, because what you're looking at is an embedded low-res JPEG that is incorporated into all RAW images to make it possible to see the image without decoding the RAW data. In addition to providing the in-camera display, that makes it easy for the operating system to generate and display thumbnails. Unless the part of the image containing the JPEG were corrupted, the display in the camera would look normal. What's more telling is that the problem may have been solved by a low-level format. That does indeed point to a bad card as the likely culprit.

So the problem is with the sd card, I thought it was with the sensor, because also when I put the camera in liveview mode, appears a lot of points and lines on the screen and then freezes And if I took the photo looks like kamerakind one
