CD-DVD Lock

If you are trying to restrict access to your CDs or DVD, or you're planning to hide some of the removable drives connected to your computer, CD-DVD Lock is one of the apps that could do that for you.
The application boasts what can be easily considered a minimal look, with options grouped on tabs for easy browsing and instant lock activation.
Once launched, CD-DVD Lock automatically detects the available drives and displays them in a simple window, with a left mouse required to lock them and thus restrict access and a right click needed for hiding them completely.
A number of options are also available and it's highly recommended to have a look in there too because this is the only way to enable password protection. Plus, you can define the number of attempts to enter a password, but also lock the drives in Safe Mode and block discs from getting ejected.
CD-DVD Lock works on most Windows versions, but we've noticed some compatibility issues during our testing on Windows 7. The program sometimes fails to launch, even when used with administrator privileges.
On the good side, CD-DVD Lock does what it says and doesn't hamper system performance at all, placing an icon in System Tray for quick access to all of its features.
Overall, this tiny program could attract a handful of users, but a number of enhancements are clearly needed to work properly on all Windows workstations. A more appealing interface and more configuration options would be great enhancements too.
