After spending a day searching the web and trying everything I could think of, I was ready to return the camera to Canon. Just before packing it up, I gave one more Internet search and found the link below which solved my problem.
I can’t prove it, but I agree with the author of the web page, Dashboard sent an illegal command to the camera and rather than rejecting the command, the camera froze. See the link for the entire article, the text which follows is an excerpt from the author.
From the web page author:
It turns out with the Canon SDK that you can tell the camera to do pretty much anything – whether it’s legal or not. For instance, you can tell it to choose an image quality mode that it doesn’t support (for example a legacy mode that was supported by cameras like the 10D but is not recognized by the 7D).
If this happens, the camera will happily accept the setting and store it in it’s internal memory. When you try to take a picture, it applies the settings from it’s internal memory, which (most likely) causes an internal exception and throws the Error 70.
