I literally tried about a million time that to format my card. When I got to Menu > USB Stick Format, it says that the format is confirmed, but when the local file browser is opened all files remain the same. What should I do?

    You've provided no OS & release details; but are you sure you're not just viewing cached files in RAM (because you failed to flush/unmount the SD card first)? The SD card maybe *toast* (no longer writable) and so changes aren't writing to it, or at least the section being written to... they are cheap/consumable media without diagnostics .. – guiverc May 18 '21 at 01:40

    Are you sure you're formatting the correct USB stick? – matigo May 18 '21 at 01:49

    You must `umount` the SD first. Read `man umount`. – waltinator May 18 '21 at 03:57

Install gparted (it is in the repository) . Put your card in the machine and start gparted. It will ask your password. THen you can see, unmount,format etc.
