This has now become a strange mystery. I am looking at the same image.

DNG file viewed in Google Picasa - I see the purple and white patches.

DNG File viewed in FastStone Viewer when I press - A. No patches.

I think there is an embedded jpg in the DNG and does get damaged. I did not even transfer the file into the computer and this is a formatted SD Card.

We need to understand how these DNGs are being handled by the computer or the software editing programs. For now the first thing I am doing is switching to PEF.

Something is fishy!

DeeDee, you can use software to extract the embedded jpeg. E.g. the software that came with the camera. Next view the extracted jpeg.

My feeling is that it's a bug in Picassa that can't properly read the Pentax DNG.

Try formatting the cards in camera. If that doesn't fix it, try doing a Quick Format in a computer. If that doesn't fix it, try doing a Full Format in a computer (takes a while to complete).
