Lock Drives is a security tool that lets you lock your USB Drive and CD Drive with your personal password.
Nowadays, almost everyone uses CD ROM/Writer/USB Drives on their computer to transfer data to/from the Computer. Mostly everyone has files or folders on their computer that they do not want to share with others.
The best way to protect your data from being taken from the system is to somehow disable USB Drive and CD ROM access on the system. Lock Drives does exactly that, and it does it easily and well.
