Why is the driver file number Driver Magician backs up different from the number it notifies me?
Some driver files can’t be found in your hard disk, therefore Driver Magician can’t back them up. The most frequently lost file is the digital signature file, which is named “*.cat”, and this file is not necessary for the device driver to function. When you restore drivers without a digital signature file in Windows 2000, XP and Vista, the operating system will warn you. You can just ignore the warning message and continue to install them. What’s more, Driver Magician will create a file named as “drvbck.pdb” in each driver backup folder, which contains driver restoration information.
