HD Guard Pro creates a small “snapshot” of the hard drive, BIOS and your CMOS. The size of that file is just 1.4 MB on a 12 GB hard drive. Your computer works as normal, and you won’t notice anything unusual.

However in the background HD Guard works to protect your computer from accidental destruction, abnormal shutdown, Windows blue screen conditions, registry errors, etc.
If anything happens with the computer, you just have to simply reboot… With the HD Guard you always can be sure to have a working computer.
