D70 not recording images
My D70 does not record on the memory card all images that I have taken, This has happened on a variety of memory cards.
Whats causes this and can it be cured
Not sure your exact symptoms but my D70 is getting old and will do the same from time to time. The problem is the Compact flash pins get dirty or lose contact. Re-seating the card firmly but gently seems to help for quite some time.
