Client formatted the 4TB Drive, after format drive was zero fill, so we started recovery with PC3k, first we made a complete image, then using Data Extractor, we recovered all files and folders completely but majority of files were corrupt including images and videos, then we repaired the some video files, in which the video shows mix of different video clips like in a 5sec clip there were 3 different video clips.
Is somebody have solution to this condition, plz reply.

Thanks
