If you know DOS or aren't afraid to do something other than point and click, 1. right click on the Windows 10 start window 2. click on Run 3. Enter this command (where the card to be formatted was my F: drive). The card might be some other letter in your system. Format F: /FS:FAT32 /A:4096 It takes quite a while to format. If you are using a laptop, make sure it's on AC power.
