Hi everyone I am Spanish, sorry for my English.|
It seems that many of us with the same problem.
I think it's Driver problem, not the format.
I found another driver and produced no error, but finished work.
The real problem we have is: the company Chuwi.
Reputable companies such as: Brother, Canon, HP ....
we have already solved the problem.
And here we are, breaking the head.
I have spoken for 3 months, with several officers chuwi services, and
Today they told me, they do not have driver of micro-sd.
