Having found out that my BV8000 Pro really wasn't waterproof, I am trying to recover all my lost data. The memory card didn't get wet and seems to be physically okay, but when I put it into a card reader the computer tells me it can't read it and I need to format the card. Same goes when I put it in my BV9700 Pro, and my tablet. 

How can I recover the data on the card? 

Hi， Is there anti-virus software on your computer? Try to turn off it.
