    I can't format it in my computer or camera. Is there anything else I
    can try? It looks fine.

    I can't format it in my computer or camera. Is there anything else I
    I mean it looks fine physically. (No obvious damage.)

    It may have fallen victim to electrostatic damage. This time of
    the year, the humidity is often low enough so you get static zaps
    reaching for things.

    Ideally, the camera (and everything else involved, such as the
    computer which is reading it) would have metal touch-plates to allow you
    to drain off the static charget before you reach for the CV card (or
    whatever other form of digital media which you may have in mind).
    Unfortunately, these days, many of the camera bodies have precious
    little metal to which to safely discharge. My Nikon D70 has (as visible
    metal) the tripod socket, the flash shoe, the strap brackets, and the
    lens mount (plus the D70 badge itself), and the shutter release
    button and surround. I have no idea how many of these are actually
    connected to a common point within the camera body (and I have not yet
    tested them with a low-current ohmmeter). I would expect the shutter
    release button to be grounded, and perhaps the tripod socket, and the
    flash shoe. Anything else doesn't get any bets either way.

    And once you are holding the CF card (or other) and reaching
    towards the socket in the computer or the card reader, do you think to
    ground yourself on the computer's chassis? (And, in a laptop, it may also
    be all plastic.) So -- you risk zapping either the flash card or the
    computer each time you connect. (Some readers have a metalization on
    the outside which may server the purpose.)

    *If* your media has suffered a static zap, I sincerely doubt
    that any data will be recoverable, and that any attempt to format will
    be successful. And static damage will not leave any visible signs on
    the outside of the card. You would need to examine the raw chip inside
    with a powerful microscope to see what has been zapped, and you would
    need to know what a static damaged chip *looks* like.

    Good Luck,
