When you run an empty usb through the wash cycle... I guess it was a "clean drive"

WHEN YOU LEAVE YOUR USB IN YOUR POCKET BEFORE THE WASHER; WHEN YOU LEAVE YOUR USB IN YOUR POCKET DURING THE WASHER; WHEN YOU LEAVE YOUR USB IN YOUR POCKET DURING THE DRYER; WHEN YOU TAKE OUT YOUR USB TO PLUG IT INTO THE COMPUTER TO FIND THAT IT STILL WORKS
