    But its not! On a 1GB memory card, I only have room for 68 photos.

    Somehow, while taking pix, I must've hit the wrong button or something.
    When I reviewed my latest shots, only 6 were on it. Card was over half

    I moved the 6, and will not take any more pics on this card.

    What can I do to make those pictures be viewed again?? I had alot on the

    What could I have done so I won't do it again?

    It was a Sony Alpha 350. I used an adapter for the SD card.

    Thanks for any help.

    Do not write anything to the card

    I had successfully recovered deleted photos from my SD card in the past with one program, I forgot the name. Try this

    It is free but it has a limit of 1Gb, suits you.

    Scan it and create a system restore point before installing it just in case.

    Could you have accidentally made the camera create a new 'folder' or
    'album' into which the six recent pictures were filed? If so, the other
    pictures will still be there, in the original 'folder' or 'album'. If you
    can read the card directly on your computer (ie not while it's in the
    camera) your file manager or image handling software should be able to
    find everything.

  4. I have this on my home computer.
    I haven't lost any photos (yet) so don't know how well it works.
    Flash memory is only good for a certain number of writes.
    Its in the thousands but when it reaches that point then
    its time for a new card.

    With wear leveling most people will never reach the limit on a flash
    memory. Even in computers that use SSD as the system drive I haven't
    heard of anyone reaching the limit to date (MacBook Air's have had SSD's
    for several years).

    Thanks, Dan. That sounds like a good thing to try. And no, haven't
    written anything to the card at all for now.

    Yes, that's what I thought I might have since it had alot of photos on
    it already for a 1GB card.

    And that's why I'm hoping something can help me retreive them
    Tried that but nothing showed. It seems to me whenever I'd put the card
    in the pc before, I'd see an extra album that was empty but it said:

    So, hopefully with Dan's tip, maybe I can recover the pics. Thanks!

    I'm also thinking of viewing the card later in the camera and use the
    Index button on it.

    The Sony Alpha 350 has the Index button to show different folders that
    holds your pics. I had forgotten about that until I was reading the
    manual last night.

    That's my last try and if that doesn't work, then I'm going to try the
    imput I received here.

    Thanks alot for everything! And I don't think I'm going to use this card
    again unless it's just for practice or something like that, once I get
    those pics off.

    Good idea.
    This is why I though you may have created a folder for the images and
    "lost" them their.
    I'd reformat the card (in camera) and do some testing. I suspect
    there's nothing wrong with it.

    The real problem is several fold:
    . the file systems use a fairly large allocation unit, say only
    about 1/32000 of the disk. (8GB = 256KB pieces)
    . the stored formats for videos and pictures should have
    unique to the card identifiers embedded in each allocation unit
    so files can be put back together even if the file system metadata
    is lost.
    . memory cards need a mode for accessing the not in use data

    You shouldn't loose more than a few seconds of video or a couple
    of images because of a few uncorrectable errors on your card.

    Camcorders with magnetic tape never had this problem. 8mm
    movie cameras didn't have this problem, even some film still cameras
    could be opened and only 1/4 or less of the images were lost.

    Please write to the camera companies to suggest that at least the
    raw formats support such recovery, and support adding codecs and
    compression techniques that support automatic error recovery in
    the case of lost metadata.

    When precious image files or important business data goes inaccessible in the memory card due to some unpredicted reason, memory card recovery can ideally be implemented. Since minute issue of corruption can bring fatal case of severe loss in valuable data, so it’s important to implement some effective commercial data recovery tools. Such tools employ powerful method that can bring back all the lost data.
