The images looked normal when viewed on the MBA. I'd guess that about 5% of the transferred images showed the artifacts. To correct the problem, I copied files from the MBA to the PC via my network. I assumed the problem with the artifacts was due to HFSExplorer. However, Jonathan's post makes me wonder what actually causes artifacts like the one shown in his image.

I have since found that the card is corrupt. I cannot read it when I plug it into my PC but I can read it when I leave it in the camera and connect the camera. I reformatted it on the PC - it worked once but it's playing up again. I am going to chuck it because it is a pain in the ....
