There aren't many apps out there that give you more control over how your CD/DVD drive door is used but CD-Door Guard is one of them.
The question is, do you really need it? Well yes if you want to avoid the problem of your CD door crashing or getting stuck. CD-Door Guard is a utility that helps you to deal with drive door errors. The program works by closing the drive's door when you forget to do it and allows you to lock it if you want to protect the door from children for example.
In addition, CD-Door Guard allows you to open and close the CD/DVD door using the mouse only and can also remind you if you've left a disk inside (very useful if you've been searching for that missing music CD). CD-Door Guard's interface is extremely friendly and removes the need to worry about disk getting stuck or doors getting jammed. CD-Door Guard is an easy to use solution for those worried about damage to their CD or DVD drive.
