Recently I decided to test some file recovery software, that is software which can undelete files after they have been deleted. These applications are very useful because sometimes users delete files and afterwards they realise that they want them back. Other times they can be also deleted accidently by inexperienced users.
The test consisted of the following:
(i) Operating System: Windows Vista Ultimate
(ii) Hardware: Nikon Digital Camera
(iii) Storage: 1GB SD Card
(iv) Notebook with integrated SD Card reader
Procedure:
(i) Using the digital camera I manually deleted over 400 pictures (around 900 MB) from the SD card
(ii) As soon as I deleted the pictures, I took the SD card out of the camera and put it in the SD slot in the notebook
Note: For any recovery to be possible no new files should have overwritten the space which was previously used by the deleted files. Hence, that’s why I decided to carry out the test immediately after the deletion.
Applications Used:
(i) Recover My Files (http://www.getdata.com)
(ii) PC Inspector File Recovery (http://www.pcinspector.de)
(iii) Recuva (http://www.recuva.com)
Results:
(i) Recover My Files: Did not detect one single deleted file!
(ii) PC Inspector File Recovery: Detected many deleted files but any picture that I tried to recover resulted in a corrupted file that could not even be opened.
(iii) Recuva: Detected and successfully recovered all the pictures. Most of the pictures were 100% viewable whereas a small minority had some parts (from the actual image) missing.
Hence, the clear winner was Recuva which moreover is 100% free software!
