I bought a 256Mb Sony memory stick from PC City, (PC World) as it’s known as out here in Spain, put it in my Samsung Digital Camera. When I tried to transfer stills from a tape, which Iv’e done without any problems before with the stick I lost. I get the message “Not Formated” have attempted to format in the camera, through my PC through USB connection, and using the camera installation disc. Has anyone any ideas Please, as to what I can try next? Would be very gratefull for any suggestions.
