Also, PLEASE make sure that you PROPERLY unmount your USB drive. On Windows, it's the little icon on the System Tray that allows you to "Safely Remove Devices". On the Mac, just drag the USB drive to the Trash and the Trash icon changes to an Eject icon. This will perform any final writes to the drive before unmounting it. Disconnecting before properly mounting your USB drive can corrupt the data and possibly damage your USB drive.
