I was able to fix the damaged USB by doing the following:
Go in Start > write “cmd” > right-click the Windows Command Prompt and choose to run it as an Administrator.
At the prompt, enter “DISKPART” to launch Microsoft’s disk management utility. It will take a second until it loads and when ready it will read “DISKPART>”.
Type in “list disk” to show a list of all disk drives. If your USB key is plugged into your PC, it should be listed here, along with other drives. Note the USB key’s disk number – you can pick it out by looking at the disk capacity.
Type “select disk n" (whatever is your USB disk number in place of "n").
Type “clean” for the utility to clean the disk, which DiskPart will confirm.
Create a new partition by entering “create partition primary”.
Choose this partition with “select partition 1", and then mark it as active by typing “active”.
Format the key by inputting “format fs=fat32". This should take a few minutes, and DiskPart will display a progress percentage.
Lastly, type “assign” to give this USB key a drive letter and “exit” to exit DiskPart.
