nikon D80 memory card problem?

    Images recently were non-readable on the computer, corrupted files.

    The long version: Newly purchased D80 w/kit lens 18-55 (I know, I need to
    add!!). Several shooting outings successfully downloaded via sandisk usb
    card reader, including shots using my old nikor lenses in manual mode.
    Yesterday, shot a series of test images using kit lens, my older 35-105 f3.5
    nikor zoom and an f5.6 300 mm tele. I judged exposures on the latter using
    the histograms in camera play mode, so I KNOW many if not all the images were
    there on card before leaving the field. Got home, placed card in reader,
    copied fine, but mac OSX only generated thumbnail for icon on first image.
    Photoshop CS2 and graphic converter refused to open jpegs and CS2 wouldnt
    open the NEFs, saying unknown file type. The file sizes looked right, about
    3M for the jpgs and 7 for the raws... (camera set to record jpg fine and
    raw). So I thought 'transfer problem', trashed the folder and attempted to
    re-copy, and mac OSX reported an error, couldn't copy files. Placed card
    back in camera and camera played only the first image, for the rest displayed
    "no image data". I shot a pic in my study which displayed fine in the cam
    and copied ok to the mac. I thought it possible that I would have turned
    the camera off while last image was still writing (doubt it, but...), but why
    should that have left 1 file (pair of files) unaffected?

    So any thoughts on any testing that should be done, should I just assume its
    a card problem(new Lexar 2 GB) and format it (I had formatted just before
    heading out), switch to sandisk or other brand cards... just wait and see if
    it happens again????? would hate to lose a whole day's real shooting!


    .... mac G5 1.5 gig ram, usb sandisk card reader, photoshop CS2, lexar 2GB
    card...


    thanks in adavance, peter

    If you cannot read the images on the card in the camera they may not be
    there.
    There are image recover utilities you can try to see if there is data on the
    card.
    If you have not upgraded the Adobe Converter in CS2 recently you may not
    have the update that includes the ability to read D80 nef files. All Nikon
    raw files say NEF but there are different formats from different cameras. So
    if those NEF files are on your computer you may simply need to upgrade the
    Adobe converter.

    It does sound like you did something to interrupt a write to the card,
    but the card may be physically defective. Personally, I would attempt
    to use a file recovery utility like Photorescue on it. The odds are
    good that you could recover all the files.

    Then I would re-format the card and test it thoroughly before using it
    for any more serious work.

    that would certainly be a good idea but I have opened lots of nefs
    already with CS2 so.... I might try photorescue

    great idea - I was sure the data was there by the file sizes....
    photorescue DID show thumbnails of many of the missing images, but I
    haven't gotten it to save yet - I think I used expert mode not yet
    registered or something... will figure it out....

    Interestingly a prior days' shots were recovered as well, which should
    have disappeared with the formating of the card!

    Gonna go buy sandisk cards, as I noticed the lexar is NOT on the
    approved list at nikon's website...

    Also I wonder about deleting the files on a card using mac OSX, dragging
    to trash and emptying trash... good idea or bad??


    Thanks!!!!!!!!!!!!!!!!

    What software are you using to take the images off the card? I would
    suggest Apple's Image Capture which comes with your computer's OS. Just
    be sure you don't have it set to erase images after downloading (for
    now).

    I use mac OSX (finder) to drag the image files to a folder on my hard
    drive, then use either graphic converter to quick slide show full screen
    all the jpegs and/or use adobe bridge to view all files including the
    nefs.

    Why use a card reader???
    The D80 has VERY fast USB2 tranfer rates, I bet better than your reader.

    Try Image Capture. Set it's preferences to open when camera is attached.
    It creates thumbnails also. I use a Lexar Card with a D80 with no
    problems.

    True, but I had to send my camera in for repair after the electrical
    connection got messed up from plugging in all the time.

    My USB 2.0 card reader is a lot slower but it saves wear and tear on the
    camera.

    Photorescue has recovered files on some of my cards that were more than
    two years old; they had been re-formatted several times in the interim.
    But you have to register the product to actually save the recovered
    files. The Nikons do not actually reformat the cards. They just erase
    the pictures. They will format a card that has not yet been formatted.

    I like the Sandisk Extreme IV cards. The camera does not write to them
    any faster, but they transfer to the Mac a *lot* faster. As far as
    Lexar not being approved, I have never had any trouble with them. There
    are a lot of Nikon users out there with Lexar cards.

    Deleting the files on the card and emptying the trash is pretty much
    what the camera does. I just find it more convenient to reformat. The
    one thing you do not want to do is to use the Disk Utility on the Mac
    to format the card unless you really know what you are doing. It is
    real easy to format the card into something unusable by the camera.

    I experimented formatting the card into different formats, removing
    partitions and creating new ones, etc., with Disk Utility. After I was
    done, Photorescue still managed to recover old files on the card.
    Photorescue will recover files out of secure folders for which you have
    forgotten the password. It will recover files from physically damaged
    cards. However, it will not do the impossible, and some files may be
    incomplete. It can also do funny things to the color balance of some
    damaged NEF files -- glowing green sky, for example. But hey, it tries.

    The D80 is faster than most readers, but not all. Some readers (such as
    the Sandisk Extreme readers) are as fast or faster and they don't run
    down the battery. A Sandisk Extreme FireWire reader will transfer files
    at 38.4 megabytes/second or faster -- much faster than any USB 2.0
    reader. (USB 2.0 is supposed to be faster -- in theory -- than FireWire
    400. In practice, however, few USB 2.0 devices live up to anywhere near
    their performance claims, and even the best are much slower than
    FireWire 800.) Even the Delkin ExpressCard 34 Compact Flash reader only
    transfers data at 20 Mb/sec.

  13. Not very surprising. Formatting only writes a new file system and an empty
    top level directoy. It doesn't affect any other data on the drive. Therefore
    your pictures are still there, just inaccessible. Like you lost the index in
    a huge library and to make matters worse someone tore the pages out of the
    books.
    File restore tools simply look at each page try to guess which pages belong
    to which book. Sometimes they find whole books still intact with just the
    cover missing (for photos on a memory card that is probably quite common)
    and then restore is easy.
    Well, depends on which definition of formatting you use.
    Low-level formatting which in case of HDs rewrites trackes and sectors is
    not available in consumer tools for good reasons.
    High-level formatting just puts some basic file system information into a
    few sectors and recreating the root directory. Therefore it appears as if
    all it does is removing files while actually it doesn't care about the old
    files at all. It simple creates a new blank root directory from scratch.

    Because it is much easier to just plug in the card than to fumble around
    with a cable that I can't find when I need it and remember to turn on the
    camera and where the heck is that tiny plug and .... No, it is just so much
    easier to use the card as a virtual HD and copy files as needed.
    Doubt that, but who knows.

    Yes, but I have several old low level formatting programs that
    were used for formatting several types of hard drives (MFM, RLL,
    ESDI, etc.) that were widely used before the advent of IDE drives.

    That's a "quick" high level format. Some high level format
    programs only do a "full" format, and they overwrite all sectors of
    the hard drive's partition that's being formatted. These can take a
    *long* time before the format completes. Other high level format
    programs allow you to select whether a quick or a full format is
    used. IIRC, some cameras also give you both format options.

    DPReview tested the USB transfer rate with these results :
    http://www.dpreview.com/reviews/nikond80/page12.asp


    Note: These tests were done using a 2GB Sandisk Extreme III SD card.
    The Sandisk Extreme IV USB reader is capable of much higher speeds.
    The fastest transfer rate uses their Extreme IV CF cards in their
    Extreme IV reader using a Firewire port, nearly 40 MB/sec. The USB
    2.0 version is slower, but still faster than 30MB/sec, IIRC. I hope
    I'm not misreporting something, because as far as I was aware, the
    Sandisk Extreme IV readers only accepted CF cards. Maybe that's the
    version that has the Firewire port. In any case, when used in the
    normal mode as a mass storage device, where the D80 appears to the
    computer as a disk drive, files are transferred *very* quickly.
