DoGoodSoft Best Disk Lock is a powerful disks lock and USB storage devices control package. It can protect your data on disks and USB storage devices from leakage.

To meet different users' need, this software provides three different lock levels - elementary lock, intermediate lock and advanced lock. After a disk is locked, it can be hidden in the computer, while the disk with advanced-lock will be hidden completely, that is, it cannot be found in any environment except in Best Disk Lock.

The feature Control USB is divided into two parts: disable USB storage devices and set them as read-only. The former can block all USB storage devices like a USB disk and external hard drive inserted in a computer, and it cannot be found in Computer/My computer. The latter allows you to read data on one of USB storage devices normally but cannot write data to it.

The program can also set the security of your system and optimize the computer system. Besides, it permits you to use tools that come with the system without extra command.
