คุณเคยใช้วีดีโอ camera รุ่นนี้ไหม

Here is the thing, I got this video camera including a taplet, and USB from my relatives from America. It was a relief that I got all this gadget because it's made my taking videos and photos a little bit easier, for my YouTube videos posting. Until today, when I used this video camera this morning, I was taking my photos and videos as usual, but I get home later, I started to used a battery charger on my videos camera and using that memory SIM card on my USB, it's turned out all my data, videos, and photos inside the video camera are all gone.

I must be accidentally erasing it somehow. The question is how can I recover all my lost data back?
