DERescue is a very powerful software to recover lost data. Please do not write any data to the partition or disk that you want to recover
User Reviews :
Strengths : It worked to recover the data I deleted from my external USB backup drive after my computer crashed.
Overall Evaluation: Overall it worked. I downloaded it and scanned to find data, and it did it. Before I could recover anything, I had to register it. That ment paying $60 to get the registration key. I think it was well worth the money. Reviewed from pcworld
