Unreadable file on Canon S 400.I used a I used a

  1. I used a Viking 256 MB CF card in my Canon S 400 camera and took about
    200 images. I can download three of the four folders containing images
    on the card- 102, 103, and 104- but I can't open or download folder 105.
    However, in the camera I can see the 30 or so images that correspond
    to folder 105, so they are on the card. Folder 104 ends exactly with
    image 500. I suspect that some kind of file information is corrupted,
    preventing me from reading 105. I actually did fill up the card, but
    threw away about 80 poor picture to make room for the additional 50 that
    I took, so in the end the card is not full. I don't believe this camera
    can't handle a 256 MB card. I used an external card reader to do the
    downloading. Maybe hooking up the camera to USB would allow me to get
    out those other images. Any thoughts?

  2. I also used an adapter and inserted the CF card into a laptop, where it
    appears as a hard drive. I couldn't read folder 105 that way either.

  4. The freeware application jpegdump by kurt steige did the job for me
    when a co-workers CF was - seemingly - empty and the "pros" at the
    camera shop couldn't do anything...

    It dumps an image of the card to disk, and the goes thru it to get
    some pics saved from the card - it works very well as long as you
    havent over-written the data you want to save or have deleted some
    "in-between" photos as that splits the picture data into small,
    incoherent piceces

    And the S400 should handle 1-2 GiB cards , or bigger... and onto a
    256 I would have guessed you could only fit about half of what you
    did manage to get onto yours? at least in a size and quality meant
    for printing and possible enlargement, and not web-use?
