Cannot format my usb

[ArrowA]

Cannot format my GENX Smart X 16GB flash USB, after it got nearly full (showing Used 15.0GB Free 30.2MB). When deleting a file, it gets "deleted" first, then reappears after reconnecting it.

1. Shutdown your computer or laptop
2. Insert USB Memory Stick into your laptop or Computer
3. Turn on laptop and then immediately start pressing (F8) key then Advanced Boot Options screen will come up
4. Select Safe Mode with Command Prompt
5. After loading files if your USB Memory Stick drive letter is (G) for example then write as
