You are here because you lost important private data, either by deleted them by accident or for some unknown reason. In order to recover these lost data, you need a computer to help. There should be other software which works as well. But TestDisk is the only software we tried, it is free and works for pretty much all operating systems. The procedure below is for windows 7, other system should be fairly similar. And this software might not work for everyone. But, give it a try and your might be lucky!
Remember, always backup contents on your sdcard, sdcards are not as stable as hard drives. Even on hard drives, you should always backup your data.
Step 1: Download the software (TestDisk) at this address: http://www.cgsecurity.org/wiki/TestDisk_Download
Step 2: Extract files to a folder. For this procedure, the files will be extracted to desktop, and folder name is "testdisk-6.12-WIP". Then connect your phone to this computer and then mount the storage. Or if you wish, you can take the sdcard out of your phone and plug into a card reader. Anyways, connect your sdcard to a computer.
Step 3: Screen shot is for windows 7, right click on testdisk_win.exe.
- Under DOS, run TestDisk.exe
- Under Windows, start TestDisk (ie testdisk-6.9/win/testdisk_win.exe) from an account in the Administrator group. Under Vista or windows 7, right-click testdisk_win.exe and then "Run as administrator" to launch TestDisk.
- Under Unix/Linux/BSD, you need to be root to run TestDisk (ie. sudo testdisk-6.9/linux/testdisk_static)
- Under MacOSX, if you are not root, TestDisk (ie testdisk-6.9/darwin/TestDisk) will restart itself using sudo after confirmation on your part.
Step 4: Choose Create, then enter (this will create a new log file, which we don't really care).
Step 5: All your computer disks should be listed here. The test is using a samsung galaxy s, so, there are two storage systems, one if the phone internal storage, the other one is sdcard. You might need to repeat these for both locations to find all your missing data. For now, we choose the 8G sdcard. And then choose Proceed.
Step 6: Choose non partitioned media. And then enter.
Step 7: Choose Advanced and continue.
Step 8: Use your left right key to choose "Undelete" and then continue. If you don't see Undelete option, go back to step 6 and choose Intel ,and then try again.
Step 9: You should see your file system now.
Step 10. Pick VideoVault or PhotoVault, and then .data or data folder. The red colored files are deleted files. For this test, we deleted some files from VideoVault private tab. So, you can see in the screen shot, the "Directory" shows "/data/VideoVault/data". And there are 4 .pss files are red. These are the deleted private video files. Pick one and then click "c" to copy. A new screen will show. Note: The new version of PhotoVault, VideoVault and MediaVault places its private files to a common place "/PssInc/Vault/.Data" folder
Step 11. This will be the destination file system on your computer. We just picked the . and then click "c" again. This will copy the deleted files to this computer location (we choose . earlier, so, it will be the folder where testdisk is).
Step 12: After the copy is finished, the screen will go back to the source file system. So, you can pick another file to copy it out.
Step 13: After you are done, come back to your computer, look at where testdisk folder, you will see a new folder called "data" is created, go in, you will see videovault and then data folder again, you will find all the files you copied out.
Step 14. These are your private files, you can copy them back to your sdcard same folder, so, photovault or videovault will recoganize them automatically.
You might need to repeat these steps if you have multiple storage location to find all your missing files. Let us know if you have any further questions.
