    What is the Class Speed Rating in SDHC cards?
    The SD Association defines 3 speed classes to help users identify the speed and performance of SDHC cards. The class speed rating specifies a minimum sustained write speed (Class 2: 2 MB/s; Class 4: 4 MB/s; Class 6:6 MB/s). You can look for the Speed Class Logo to identify the performance class of your memory cards and host devices.
    What is the difference between TransFlash ( T-Flash ) and microSD cards?
    microSD is a format for removable flash memory cards. It is derived from SanDisk TransFlash and is used mainly in mobile telephones, but also in handheld GPS devices, portable audio players, video game consoles and expandable USB flash memory drives. TransFlash and microSD cards are the same (each can be used in devices made for the other).

    I placed pictures on my Flash Memory Card but why can't I see them in the digital camera?
    Cause : You have modified the pictures or you have placed them in a folder other than the one the camera uses.

    Solution : If you have modified the pictures, most cameras will no longer be able to see the pictures. In the future do not modify the pictures if you need to see them again with the camera. If you placed them in the wrong folder, please put them in the folder you originally found them in. Most cameras will only use the folder they create to see the pictures.

    I keep receiving "card error" message whenever I turn on my camera with the flash cards in. I've removed the card several times and put it back in but I still get the "card error". According to the camera's instruction manual, I might need to format the flash card if this occurs. How do I do that?
    It is true that the format on the card may be corrupt. This will happen if:
    • The card is removed from the camera before the camera is finished writing to the card
    • The camera is turned off before it is finished writing to the card
    • The camera's batteries run dead
    • The batteries are running low (especially if you are taking rapid photos)
    • The incorrect batteries are used in the camera. (see the camera user guide or manual for more info on batteries)
    Format the card using the camera's formatting utility if possible. Since the format on the camera is not always sufficient to correct this, the card can also be formatted in PC ( an USB Card Reader might be required ). Just format the card like you would a floppy Disk. In My Computer, right click on the drive letter for the card and select Format.

    WARNING: Formatting your card will erase all data on the card.

    What do 80X, 120X and 133X on CF Card labels mean?
    Like CD-R, X stands for speed. 1X stands for 150Kbytes/Sec while 80X stands for 12 Mbytes/Sec. Manufacturers calculate speed differently. In general, "Sustained write speed" is approximately 2.5Mbtes to 3.5Mbytes/Sec. or 16X~25X, "Sustained read speed" is 6Mbytes/Sec. ~ 12Mbytes/Sec. or 40X~80X. Thus speed ranges differ quite a lot depending on the method of calculation.
    What is the different between FAT16 and FAT32? Which format should I use to format my memory card?
    The File Allocation Table (FAT) stores the information, such as the filename, location, size, etc. required for a user to access their data. FAT16 uses file allocation table entries that are 16 bits in length. Hard drives using FAT16 are limited to 2GB partitions. FAT32 was developed to break through the 2GB restriction, while still being backward compatible with FAT16. FAT32 is able to support volumes up to 2048GB. Most personal electronics today using flash memory use FAT16. If you are not sure whether or not your device supports FAT32, we recommends formatting the flash card to FAT16.
    What is the difference between CompactFlash Type I and CompactFlash Type II?
    CompactFlash Type I is 3.3mm thick. CompactFlash Type I is forward compatible and will work in all CompactFlash Type II slots.

    CompactFlash Type II is 5.0mm thick. CompactFlash Type II will not physically fit into CompactFlash Type I slots

Using a Duo adapter, M2 can fit into standard-size Memory Stick Pro Duo. MS Pro Duo and M2 are useful for recording real-time, high-resolution moving images.
