My micro 64G SanDisk only reads a few kilobytes. it if for my Go Pro Camera. It's brand new but when I put it in the camera it says no SD card. When I take it to my computer, it shows the DCIM folder. It won't let me format it or restore to default. just shows 512 bytes 1.00MB. My other 16GB card of a different brand works fine. Any help for this?
