Sure. Try a matching filesystem format on your MicroSD card: FAT32

This is the recommended way to format the microSD card by the display manufacturer DWIN for Windows OS:

1. Start - run - input “command”(“CMD” for win7) to enter DOS system;
2. Input command: format/q g:/fs:fat32/a:4096 (Note that q is followed by a space). Click enter after input.

Good luck
