"Windows cannot complete format"error or other similar error "Format not completed successfully" may occur due to Windows or USB drive itself, such as virus infection, bad sectors, disk write protection, storage device corruption, etc. There are two quick options to solve this problem.
Before you begin, let's learn about the possible reason why Windows fialed to format USB drives. This issue can be caused if any of the following situations exist:
Cause 1: USB driver problem
