OK we have a landing!
The third card an old 2 GB card works.
I deleted the content on the notebook. Then formatted it in the notebook. The camera recognised it and allowed me to format it in the camera.
It works.
Now formatting the other two (4 GB) disks in the notebook and then seeing if the camera accepts them.
I was thinking about getting a larger disk but from what is said here maybe prudent to sick to 4 GB.
The main thing is the camera is working. SD cards are cheap enough to replace.
Still puzzling as to what happened to both my 4 GB disks at the same time. They were working on Monday and are still working in my notebook.
