EOS 5D Mark III Producing Corrupted Images

[Cailinnua]

I have a Canon 5D Mark iii camera which keeps producing corrupted images as attached. There is no pattern to these images being produced, I am using the same lens and settings and might take 200 images with 3 corrupt and 30 with 10 corrupt. I have attached a sample of images being produced. Sometimes they have these colour blocks, sometimes less or more of the photo is covered, and sometimes black

Are you using both card slots? If your using both cards with the camera set to "record to both cards" the corrupted images would be on both cards.
