I love this software. But I could not restore MKV file on a hard disk with WD Caviar Green 3TB GPT NTSF, lost partition. He restored several AVI, very good. I think any software in the world cant restore MKV in these conditions. I tried various software, some with many megabytes, and believe me, the best was Recuva It would be great if Recuva do this. Thanks, Shakes from Brazil..
