It is an ex memory card

probably not just resting ...

Very odd - after months of faultless service this CF card threw a bit of a wobbly a couple of evenings back and now the camera won't format it and the PC won't acknowledge it's presence ....

Emergency blip as I spent the day travelling to a family funeral,  although the departed had enjoyed a good life and clearly achieved a great deal, so not as sad as it might have been.
