USB drive is a great tool for you to bring your data anywhere you go without having to lull the whole computer along. The bad thing is, it is small in size and can easily be misplaced or stolen by others. When such incident occurs, the last thing that you want to happen is to let others view your confidential data, and probably do something bad with them.

In Windows 7, there is this new Bitlocker To-Go function that allows you to encrypt your USB drive. In the event that your drive is stolen, there is no way that others can access your data, unless he/she has your password.
