Have a 2 month old Lexar 80X CF card that just died on me. It is a 1 G card that was given together with the D70s. After about 60 shots, there was an error om my lcd screen. After reformating e card , the problem still exists after the same 60 shots. Therafter, I cannot take any pictures. Anyone here who has the same problem like me? Pls advise. What can I do now? where can I change the card?
