Recovering deleted photos from flash chips

    I see that there are a number of programs available that recover deleted
    photos from flash memory.

    Does anyone have any opinion on what the best is?

    I'm currently trying out 'Easy Digital Photo Recovery' Version 1.1.

    It seems to have found a picture I deleted for test purposes. To
    actually recover it, you need to register the program for $29.95. Not
    bad, and the program is easy to use. The only reservation I have about
    it is the opening screen where it shows the various memory devices
    detected. It shows my 2GB FAT formatted SD chip as a 1GB NTFS formatted
    chip. It apparently reads it just fine and found the deleted file. I'm
    just wondering if there might be anything else wrong with the program so
    that I should stay away from it.

    Thanks, Gary

    I've had no problems with either the free program PC Inspector or
    LexarMedia Image Rescue 2 which came free on one of my older Lexar CF
    cards.

    Well, just doing an undelete on FAT is trivial.

    It becomes much more challenging and interesting when the directory
    entry has been reused or the whole directory becomes corrupt and the
    program has to recover the file data by searching and investigating
    the data blocks.
    No, I never had to do that myself, but it is something to keep in mind
    when getting a file recovery program. Can it handle corrupted
    directories?

    Although I have been fortunate enough to never loose files on a flash
    card, I can highly recommend R-Studio as a general file recovery
    application. I've been forced to use it three or four times now and every
    time it's done a great job.

    Recovering deleted files from a FAT filesystem if no writes have occurred
    is not a terribly challenging task. In the past, I've written utilities
    that are capable of doing that. Deleting a file on a FAT filesystem
    consists of setting a few bits which mark the corresponding blocks as free
    - the information in the File Allocation TAble as to what constitutes the
    file are still intact. There should be a couple dozen freeware utilities
    to do that.

    Thanks for the advice. I have purchased Lexar Image Rescue 3. It works
    great. I tried several freeware programs, but it seems that you get
    what you pay for. I was able to run the Lexar program without resorting
    to reading the documentation. I was not able to say that about the
    freeware programs.

    This is not totally true

    When a FAT file is deleted, the File Allocation Table is also cleared
    down, so fragmented files are harder to reconstruct. For FAT12 and
    FAT16, the pointer to the start of the file is valid, and if the file
    is sequential, recovery is easy.

    For FAT32 the problem is worse as the higher 16 bits of the cluster
    number is also deleted. As the file pointer is not complete, the
    address of the file/photo is not precise. Many recovery programs
    ignore this and so cannot recover files from deleted FAT32 drives.

    Very few programs will attempt defragmenting deleted FAT files.
    Fortunately, not many photo files are fragmented, but if your most
    important photo is, then .... On a 2GB memory chip I recovered today,
    50 out of 500 were fragmented

    Hi,

    I had 100 or so images deleted by a computer, inadvertently, from an SD
    card, including 36 from a friend's wedding.Several programs, both free
    and paid for, did not recover any pix, but eImage Recovery did recover
    most, including 34 of the 36 wedding pix.

    I used the freebie software that comes with new Sandisk cards on an
    old CF card that had been formatted at least ten times. It recovered
    all the old shots from a year ago that hadn't been physically
    overwritten.

    I would suggest that as a good free one. I purchased PhotoRescue prior
    to trying Recovery Manager. They both do similar job, PhotoRescue might
    be marginally better.
    These programs work quite well even if card has been formatted. I've
    only ever tested recovering .jpg files.

    I've not looked at FAT32 - you're probably right. All the cards I work
    with are 2gb or less - hence FAT16.

    That's a good reason to not delete photos from a card. I tend to shoot
    until it's full, download and then format in the camera.

    As a follow-up to my recent post, I tried Vaiosoft Recovery Manager for
    my "deleted" images, and it recovered exactly zero. E-Image Recovery
    fully recovered 32 of 36 images from this card. Perhaps you do get what
    you pay for.

    Good luck.
