Formatting a pen drive, Kingston USB drive, SanDisk SD card, Samsung USB drive, or Transcend pen drive is a quiet easy process. For some reasons, we need to format pen drive into the right file system. But sometimes you may encounter the error “Windows was unable to compete the format”, and you cannot format pen drive successfully. Most reasons that result in this phenomenon can be a virus infection, bad sectors, write-protection or physical damage. If your pen drive has ever been used on a device infected by a virus, it may get virus infected too. As you know, formatting is a writing process. So, you cannot format the pen drive if some of the sectors are damaged or the pen drive is write-protected. If the pen drive has some serious physical damage, you cannot format it too.

If it is still write protected, follow the steps below to remove the write-protection.
