D40 and memory card errors.
I was using the original Nikon battery that came with the camera. 5 years old and still going strong.
Since it was mentioned that perhaps a battery could be the culprit.........I might question a 5 yr old battery still being strong.... I have some D50 batteries that still seem to be good, but thats a long time for a battery.
