Additional Compatibility Information

Card Format

Cards purchased after August 2008 are formatted as FAT32; our contemporary data loggers require this format for the card to work as expected. Cards purchased before August 2008 were formatted as FAT16. Our CC640 camera (retired), the CR9000 dataloggers (retired), and CR5000 dataloggers with older operating systems need the FAT16 format. A card formatted as FAT32 can be reformatted as FAT16.
