As handy as USB thumb drives can be, their small size makes them easy to lose. Tim Fehlman, of Daily Cup of Tech, has worried about the possibility and come up with a clever solution. He explains how to install an auto-executing program that will automatically pop open a “Send Me Home” message if your lost drive is plugged into a computer. He even suggests offering the finders a brand new thumb drive that is twice the capacity of the found one.
