Most like you has the data corruption and loss, common causes are;
1)Power outages or other power-related problems.
2)Improper shutdowns, pressing and holding the power button, and hardware problems or failures.
3)Failure to eject external hard drives and related storage devices before disconnecting them or powering them off.

You need to recovery your files , check the link for free softwares, and use the "Recuva"

I did have same situation and lost my files too, what I do now I save the important files into two difference HDDs.
