Hello,
I got my Jumper EZBook Pro 3 from Gearbest 6 weeeks before. At first everything worked smoothly. But since 2 weeks my 128GB SD Card from Sandisc does not appear in the Windows explorer anymore. Windows shows the SD Card as a Sandisc device, but this is all. I cannot work with the disk anymore. It seems the card reader and the driver are both ok, but the device is not mounted anymore.
I tried it with other SD Cards, but they all were only recognized but not mounted.
Has anyone an idea how to solve this`?
