    My wife has a camera and took a load of pics of our daughters first birthday with them.

    I think I loaded them into iPhoto, but they're gone, possibly because I recently copied the iPhoto library back from my external hd to my MacBook to get some photos I needed (ironic isn't it?). I normally delete the photos from the camera after import, but I don't know if it was formatted. The upshot is they're gone, and I'm not the blue eyed boy at the moment.

    Anyway, the camera's hardly been used since (1-2 pics), so I was wondering if there is a way to get the photos from the SD card, or are they a lost cause. I still have a couple of photos that I took on my camera, so it's not the end of the world, but the better photos are on my wifes camera (she had time as I was cooking, playing with children, entertaining adults, drinking myself silly etc).

    If you can help, you might just save my sanity :eek: .

    Photorescue at datarescue.com does the trick for me. I have used it many times to get photos that were gone for good. Not free but cheap to recover priceless memories or blackmail material.

    Looks good. I like the guarantee that you'll get the photos you see on the previewer or your money back. I'll download it and when I get hold of the card I'll give it a whirl.

    Cheers to you both - I might be allowed into the house this weekend.

    i personally have used data rescue II to get some pictures back. MAKE SURE you don't put anymore pictures on that card, it may over-write the ones you are trying to get back.

    That worked a charm. Thanks for the advice.

    Am I right in presuming a 7 pass erase in Disk Utility will prevent the older "less flattering" ones from ever being recovered again ;)

    Just FWIW I just went through this and while it did a great job at recovering the JPEGs it didn't manage to recover the mini-movies I was really after even though there were he correct number of movies in the preview.

    I was able to recover the movies manually using a hex editor. Perhaps the MOV format used by the Lumix FX-01 I have is non-standard?

    Another tip if you want to give these tools the best chance possible is not to delete individual pictures on the card, and to reformat the card semi-regularly. This practically guarantees that the pictures will be in contiguous blocks on the card, greatly simplifying the task.

    So I have a memory stick camera that I imported pics and movies to iPhoto and three very large movies didn't import for some reason. I need to try and recover them but I see you didn't have luck except with Hex editor??? Could you advise me how to get these three movies back please.

    Here's what I did (in broad strokes).

    First I created a complete raw image of the memory card using the "dd" command.
    Launch Terminal.app
    Run "dd if=/Volumes/Stick of=~/Desktop/file.raw
    This will leave you with a file names file.raw as big as your memory stick on your desktop.

    Next, locate a movie that you downloaded successfully and didn't modify.
    Open the file up in a hex editor.
    Near the beginning of the file you'll see some signatures of the file. you might see an mdat or moov string or maybe even the name of the camera.
    Note the offset of the signature in the file.
    e.g. if you see mdat as the 6th character in the file, remember that.

    Next, load the raw image file you created into the hex editor.
    Search for the signature you found in the good file.
    Step back in the file by the number of bytes you recorder earlier.
    Trim anything before this point.
    Save the resulting file as raw1.mov

    Load into QT Pro.
    Play the movie
    Save the movie as a new MOV file, say output1.mov
    Record the size of the resulting file.

    Now you'll want to repeat the process on the last raw file you had (e.g. raw1.mov) instead of file.raw.
    You should be able to skip about as many bytes as the output1.mov file you got out from the last step before looking for the signatures again.

    Note that this only works well if the card was pretty much empty before you started using the mini-movie mode, so that the data is written to the card sequentially. Which is why I try to avoid deleting pictures individually and will reformat the card peridically.

    Wow, you know your stuff- I will try this when I have some more time later this week. Guess I need to buy QTPro!

    thanks for taking the time to type this out!

    Almost 30 yeas of hacking file systems with a hex editor pays off sometimes. ;)

    You don't need QT Pro unless you want to clean up the files you get out.

    If you get the file after the first cut to play in QT you're 95% of the way there...

    Okay, I'm not even close to being a Terminal/Hex Warrior like balamw, but I had the exact situation happen to me, and I tried TestDisk (as well as many others). It was unsuccessful at first, but after I grabbed the updated version, it worked like a charm. It recovered JPEG files as well as the AVI mini movies I shot in the delivery room.

    The link is: http://www.cgsecurity.org/wiki/TestDisk

    Download and unzip the file (version 6.5), and follow the instructions. I can't remember the exact steps, but it wasn't too hard to figure out.

    HTH.

    Believe me, manual recovery's not my primary tool either.
    Interesting that this did anything for you as it's targeted as a partition recovery tool not a file recovery tool. [Downloaded and added to bag of tricks. Thanks!]

    I know. I had tried Photorec originally, but had no luck with the AVI files. The files were inaccessible after trying to use the camera in conjunction with the iPod photo attachment. Since all the files were lost--and the card was shelved pending recovery, it wasn't really overkill.

    My pleasure.

    I had something similar happen to me. I was shooting a street hockey tournament and one of my memory cards crapped out. Couldn't get the pictures off at all. Ended up shooting the rest of the tournament with 1 card. (I now have 3) I bought Media Recover. (I think) I'll check when I get home. It worked great and got all of the pictures back from the card.

    Edit: Yep, MediaRECOVER is what I used.

    Does anyone know anything about the ability to recover corrupted files?

    :(
    I'm experiencing problems of that sort, myself...
