I accidentally deleted the wrong video off my goPro and subsequently the sd card. When I got home I tried a few different recovery software's but none worked prior to finding out about Recuva and it worked for a couple videos but the one I wanted is showing as a yellow dot and poor. When I recover it, it says partially because it was overwritten by some weird file E:\mdb_h7.bk. Anyone know anyway to find the rest of the file or what I can do?
