Instance 2:u disk Long "write protection"
Since the computer can be used to prevent the USB drive away privacy, then we can be their own U disk also protected it? Of course, it is not the traditional way to write the protection button on the U disk, but to adopt a new method. Windows XP SP2 introduces a security feature for USB devices that allows users to add "write-protected" functionality to the flash disk, preventing changes to the contents of the U disk.
The method is simple, expand [Hkey_local_machinesystemcurrentcontrolsetcontrol] in Registry Editor, and then create a new name in the control item named " Storagedevicepolicies, and under the subkey, create a new DWORD value named "Writeprotect" and set its value to 1 (hexadecimal). Exit Registry Editor to take effect.
In this way, when someone wants to modify the data in the U disk on our computer, a warning window will pop up to tell you that the U disk has been written for protection (see Figure 2).
★ To restore the Write function to the flash disk is also very simple, you need to change the "write Protect" value to 0.
