Warning doing the operation on the wrong disk will cause you more issues
In windows the most reliable way is to use the CMD prompt and run diskpart
list disk make a note of which is the USB disk - you can usually tell easily by the reported capacity. select disk N - replace N with the drive number from beforeclean - this should then make the disk acceptable to any system for formatting.On linux you can accomplish the same thing by running:
dd if=/dev/zero of=/dev/sdN bs=1024K count=1
Where n would be a, b, c..

You mention Device Manager, is this Windows? Or Linux? For Windows, you could use Rufus - http://rufus.akeo.ie/ and I have had good luck with it. I know there are USB Tools in LINUX Mint.
