Compact flash working on PC but not on Camera

Discussion in 'Digital Cameras' started by Need a little help please, Oct 25, 2005.

  1. Hello everyone,

    This is a problem that I originally posted on: uk.comp.homebuilt on
    21/10/05, with the same subject. Unfortunately, no one has been able to
    resolve the problem, despite their best efforts.

    I'm hoping someone here can shed some light or offer some guidance.

    Jenoptik Digital Camera JD3300Z3 3.3MegaPix, 3x Optical Zoon
    Kingston 512Mb Compact Flash Card

    The camera still works perfectly with the 32Mb Compact Flash it came with.
    The 512Mb Compact Flash works in so far as it can be accessed and written
    using Windows / Linux through a USB card reader.

    Basically, despite working perfectly previously, the camera no longer
    recognises the 512Mb card and refuses to start up with it inserted,
    eliminating the possibility of formatting using the camera, as this can only
    be done using the menus. No start up, no menus. The camera just locks up
    after switch on. Only way to power down is to remove the batteries.

    The problem occurred after formatting the card in Windows XP. It simply no
    longer functions in the camera.

    In an effort to resolve this, I have tried the following without success:

    Using Windows Me, formatting with FAT filing system.
    Using Windows Me, formatting with FAT filing system, and adding the folders
    usually present on the card.
    Using Windows XP, formatting with FAT filing system.
    Using Windows XP, formatting with FAT filing system, and adding the folders
    usually present on the card.
    Using Windows XP, formatting with FAT32 filing system.
    Using Windows XP, formatting with FAT32 filing system, and adding the
    folders usually present on the card.

    Using Linux, erasing the card from root shell using: dd if=/dev/zero
    of=/dev/sdb bs=512 count=1048576
    (sdb is the compact flash card) and attempting to format in the camera.
    Camera would not start up, so unable to access formatting option in the
    menu!

    I'd appreciate any constructive help anyone can offer on this matter. Thanks
    in advance.

    As a guess, all of those FAT formats the you performed using the
    computer were FAT32, and the Jenoptik camera only recognizes FAT16.
    You should be able to reformat the card with a FAT16 file system,
    and if that works, it's best from that point on to never use
    anything other than a camera to format the cards it uses.

  3. Hi ASAAR, thanks for the reply.

    Windows XP gives the option of FAT & FAT32 to format. I tried both.
    How do you format with FAT16?

    FAT should be FAT16. If that was unsuccessful I don't know what
    else would work, but you could see if you're running into a limit to
    the size of the disk volume that your camera recognizes. See if the
    camera's manual mentions the largest card size it recognizes, as
    that may be a guide. It may also have a phone number or email
    address to use for product support.

    You could try using less than the card's maximum amount of space
    by formatting a 100MB disk volume. If that works you could either
    try again by formatting a 200MB volume or quit while you're ahead
    and try to have the camera reformat the card. If even that doesn't
    work, I'd then try to locate a disk utility program that removes the
    card's partition table (which contains the descriptors of the
    formatted volumes) and see if the camera then is able to recognize
    the card. My guess is that if the problem is not size related, when
    you initially used XP to format the card, it redefined the format to
    a type not recognized by the camera. There are primary partitions
    that contain a single formatted disk volume and extended partitions
    that can contain many logical disk volumes. If you can temporarily
    get the use of another brand of camera that also uses CF cards (from
    a friend or a camera dealer) you could try using that to reformat
    the card. As a last resort, there are disk utilities that are used
    to clone disk drives. The only problem is that if you use it to
    produce a cloned copy of your 32MB CF card onto the 512MB card and
    it allows the camera to recognize the card, you may be stuck with a
    512MB card that even after being reformatted by the camera, is
    limited to 32MB. Then you might go one step further and use a disk
    utility to expand the size of the disk volume. "Partition Magic" is
    one of several commercial disk utilities. But using it is best done
    by someone that has some experience doing that sort of thing.

  5. Thank you Joseph for the reply,

    I would love to use the camera to format the card, but as I stated
    originally I cannot do this:

    "despite working perfectly previously, the camera no longer
    recognises the 512Mb card and refuses to start up with it inserted,
    eliminating the possibility of formatting using the camera, as this
    can only be done using the menus. No start up, no menus. The camera
    just locks up after switch on. Only way to power down is to remove
    the batteries"

    The manual reveals no information on special formatting.
    The software supplied offers no facility to format the card, only retrieve
    images.

    Whilst the card may well be faulty, but it is difficult to understand why it
    works perfectly when connected to the PC via a USB card reader, which also
    works perfectly.

    The camera may be faulty, but again its difficult to understand why it works
    perfectly with the original 32Mb card.

    The problem is making the camera and card work together happily again.

    Type format /? for all the options.

    C:\> FORMAT <volume> /FS:FAT

    where <volume> is the drive letter of your card. It would be N: on my
    system.

    What happens if you run a CHKDSK on the card after formatting? What are
    the results?
