Compact flash not being read by card reader?

Discussion in 'UK Photography' started by David Chamberlin, Jan 13, 2006.

  1. Hi all

    Not sure whether this is a photo issue or a PC issue, but the boundaries
    are a little blurred!

    I tried today for the first time to read a CF card from my KM5D directly
    in a card reader, rather than via the camera connected via USB. (The
    latter works well, but is a bit slow, so I thought I'd try the reader to
    see if it's any quicker.)

    However, when I placed the card in the reader, windows explorer
    *eventually* told me the disk in drive F was not formatted, and would I
    like to format it now. Obviously I clicked 'no' and removed the card,

    I'm now in the process of downloading the photos via USB with the CF
    card safely back in the camera. Any ideas why this should happen? (Sony
    memory sticks from my compact camera work fine in the reader.)

    Many thanks

    Do you have any other CF cards that can be read in that reader?
    What is the OS?
    Can you get a working CF card in the reader (formatted if necessary) working
    in the camera?

    Hi David,

    Only thing I can think of is if you never formatted the card in the camera
    when you first got it. Once you've downloaded via camera, format card in
    camera then have a go with the card reader.

  4. I only have the one CF card at present (which works fine in the camera),
    as I've only just got the camera, and my other devices use Sony memory
    sticks and SD cards. The reader works (and very quickly) with both MS
    and SD, although obviously in different slots ;-)

    The OS is Win XP home SP2.

    I'm now guessing that the camera has formatted the card in a way that XP
    can't read directly without the camera software intervening. I must read
    the instruction manual again!

  5. Hi Stephen

    Tried that, no luck. I reckon the card reader is broken, or at least
    there's a fault with the CF slot. When I buy further CF cards, I'll be
    able to compare them. Until then, it's going to have to be slow
    downloads via USB.

    Chances are, if thats the case, that it will work in the other direction, eg
    formatted in PC will work in PCa nd camera. unless there is something v
    unusual about this camera. You could always try when its empty.

    Hi David,

    As a last thought do you use any software for downloading via the camera?
    maybe this is causing conflict with accessing files via card reader and
    maybe try software used for camera to access the card reader direct. Then
    again as you are using XP you probably are'nt using any Canon software.

    Another option is to try card & reader on friend/relative's pc and see if
    the same happens. Also make sure no pins are bent or missing in card reader
    if you have not already done so.

    David Chamberlin was thinking very hard :
    I'm new here so I won't jump in with both feet, but is the card larger
    than the reader can handle. I have a card reader and it will only
    handle cards up to a given memory size.
