When I make a partition & a new windows then my pen-drive was in USB port. After completing a new windows my pen-drive can't be open. Windows recommend to format it but it could't be formatted. how can I format it now
The suggested method usually solves these kinds of issues. I would recommend you to try formatting the drive while in Safe Mode and while using another PC. Do you receive an error message while following the Diskpart commands? Please open Disk Management and check if the drive appears with a proper file format and drive letter.
