I have tried clean all command in Diskpart and it took an hour to be completed but at the end nothing has changed. I think the SD card is locked and when I try to format or re-partition the disk, either it will show a successful result or it will return "Windows was unable to complete the format" error. I have tried to format it in Linux (this answer ) and Android as well but no luck. Is there a way to reuse my SD card as a portable storage?
