Color smearing on occasional images

I shoot 14 bit RAW only and have an occasional file that has color smearing along the lower half of the image. The only clue I have is that it seems to be associated with the first image I take after turning on the camera. It's funny that I do not see it in Lightroom CC Library mode but I do see it in Develop mode. It shows up if I export to jpeg from either mode. I checked the integrity of the memory card and it is OK. Hope someone has an answer. Maybe I am too quick on the trigger or is there some problem there?

That looks like a corrupted file. Have you tried another memory card, it could be a bad card. Also, do you see this both on the computer and the camera back display? That could also give some clues as to what is going on.

Thanks, woodyg3. I ran some memory card specific software designed to identify errors, defects and fake cards. It came back clean. I did think about viewing them on camera but I do not remember seeing anything like that but when I am shooting, I do not look at each image. I wonder if I copied the defective RAW files back onto the card, would it be the same as the camera writing them. I will give it a try. Also, as I said, it tends to be the first image after I turn on the camera. Maybe I am rushing the shot. I might see if I can force the error to re-occur. Thanks for replying.

Crazy because I just looked at the files again.Windows photo viewer displays the .NEF images just fine but when I look at a jpeg exported from LR, they are corrupted. I just tried to cause the error but so far I cannot.

You'll need to use the process of elimination. Replace the cheapest link in your chain of processing. This is usually the USB cable. Replace that, and see if the issue goes away.
