When I received my Ender 3 pro I was excited to print the same models that came with the printer, but when I put the card in, it would not read. So I plugged it into my pc and it read the data fine.
So I copied all the files to a folder on my pc and copied all the files to a local folder. I reformatted the card and copied back the gcode files that I wanted to print and it worked!
