For whatever reason, you decide that formatting the flash drive will solve the accumulated problems, but you do not know how to do it.
Instructions
Step 1
Connect the flash drive to one of the USB ports. Open "Explorer", "My Computer" or any file manager (for example, Total Commander). Find the flash drive in the list of disks and right-click on it. In the context menu that opens, select "Format …".
Step 2
Set the desired formatting options (capacity, file system type, volume label, formatting method) and click "Start". Wait for the end of the formatting process. Its duration directly depends on the selected settings and the size of the flash drive.
