DVD Device Lock 严格限制对 CD，DVD，floppy，USB 等设备的访问。你可以隐藏设备或者限制访问。

The program can be used to restrict read or write access to removable media devices such as CD, DVD, floppy, flash and USB drives. You can also restrict access to partitions of hard disk drives. You are given two choices when you secure your data: you can hide your devices or lock access to them. Access password has to be entered to gain access to the devices back. This software will never endanger your protected data. If you lose or forget your password, you'll never lose your data stored on the protected media. Moreover, it works much more faster than any other software using cryptooperation mechanisms. The main purpose of the program is to restrict an ability of copying data between removable media and hard disk drives. You can also deny access to the media itself. This program also allows you to avoid many of headaches connected with unauthorized software installations from any removable media and it prevents data leaks through removable media.
