The mp3 player ate my homework

July 16, 2006 4:37 PM

My cheapo mp3 player broke the win32 file system on my flash card, and so destroyed the pictures I had stored on it. How can I recover them?

Here is what I think happened.

I used the 1gig SD flash that I usually keep in my mp3 player to take some pictures, including one of the best sunset shot I ever did, looking down into the Newport Bridge. I brought the card back to the mp3 player to play some music, but when I put the card back into the camera to download the pictures to the computer, the pictures were gone.

Now, if I put the card back into the mp3 player, all sort of weirdness happens: directories with files as seen from Linux are empty as seen by the player.

I suspect the mp3 player is to blame. It is a cheap Lexar thing. The next thing I did was to make a dd backup of the file system, then run fsck, but it didn't report anything.

I've been googling for a Norton Diskedit clone for Linux, but I couldn't find anything. It would be great to go in the backup and see whether the pictures are still somewhere in there.

I found a program before that would scan flash media for JPG data (thus pictures that were not indexed by a filesystem). There was a free trial, and the trial would actually let you save an image the card itself, so that you could re-use the card and then recover your data after buying the real version (which isn't too expensive)

I think this is it, but I'm not sure. Looks similar.

It's not photo-oriented, but I've had good results with Restoration.

Here's an article addressing your question. It recommends a free tool. I haven't tried it, not having yet been in this situation, but the article praises it. Worth a try, anyway. Post a follow-up on the thread if you're successful.

TestDisk & PhotoRec sound like the best bet.

Most file recovery software just looks for files marked as deleted by the file system. PhotoRec works at a lower level and can recover things when the file system is badly damaged. It also works on linux.

Flash File Recovery may also be the program people are thinking of. I've seen a recommendation for one of these on... I don't remember where. Kenrockwell.com? photo.net? One of the DC review sites?

Damned if I can remember; I've been lucky so far.

PC Inspector Smart Recovery spent the night reading my flash card and did not find anything. Restoration looked too amateur and I couldn't get it working.

I tried TestDisk & PhotoRec next, and it was wonderful. It worked off of my dd image file, and within five minutes it had recovered all the pictures.

I will post the sunset picture on flickr as soon as I get home.

Thanks everyone.
