Install free tools to possibly recover media card files Apps
I may not be the first, nor the last, but when someone you know loses pictures from their memory card, the only thing you can do is help -- espcially when the card contained wedding photos!

After some searching, I found a site thats presents a solution for data recovery on OS X from external media, such as memory sticks, SD cards, etc. The author of that page located a couple of free and open source programs (TestDisk and PhotoRec), and he discusses how to use those programs and what files they may be able to recover.

I followed the instructions on the above site, downloaded the package (522KB TestDisk/PhotoRec download), and installed it. It's a command-line program, so no GUI, but it worked like a charm after installing it in Terminal:
./configure
make
sudo make install
Note that a reboot is required after installation. Also, it will never write to the media it's trying to recover, so there's no danger of further damage. It really helped me recover the missing wedding pictures.

Install free tools to possibly recover media card files

When this happened to me, I made a disk image of the card first. Not because of corruption worries (most, if not all, of the utilities out there only read and never write), but because working with a local disk image works manay times faster than an old usb card reader...

If you prefer a Mac OS X GUI to recover trashed pictures, try EXIF UnTrasher

I've had some luck in the past with the freeware "Exif Untrasher" which has a proper GUI and has worked the one time I needed it.

Available at the usual sites - definitely through MacUpdate.

As for prevention, I'll repeat the boring stuff that may or may not be *true* - don't delete any files on the card using your Mac or PC - use the camera's own facilities to avoid corruption. Exactly how that effects things like iPhoto's delete after import option (a highly UNrecommended option anyway) is an interesting question!

If the free utils don't do the job (and the one or two times I've tried them, they did do the job), commercial data recovery utils like Data Rescue, and maybe Diskwarrior, will usually recover files from memory cards.

PhotoRescue by DataRescue is really worth the money! This tool just rocks!

If you want to rescue your data, BE SURE to do create a disk image, but be careful, MacOS X creates some files on the image and might overwrite some deleted data. Check c0re weblog for some hints. (for SD cards: just lock them).

photorec vs. EXIF-untrasher
Authored by: tatilsever on Feb 12, '06 02:45:25PM

Well, I used both photorec and EXIF-Untrasher to recover an accidentally deleted file. First of all, photorec is not exactly a command line utility, it has a text based UI, just like pine or pico does, so it is pretty easy to use. Neither of them recovered the file I was looking for, but photorec recovered about 18 files vs. 8 by EXIF-untrasher. Besides, 2 of those by EXIF was so corrupted that Preview could not open them. Photorec also seems to be looking for more than just JPEGs, actually whole bunch of file types such as doc, avi etc. Unfortunately, I have deleted my avi files along time ago, so I could not test whether photorec could actually recover any. The only issue I have with "photorec" is that it writes a settings file and a folder with the recovered files in my home directory. I wish it asked me for a destination first, but beyod that it is a fine program.
