Solve the problem.
If you cannot find it in the registry, refer to the following:
Instance 2: USB flash drive "Write protection"
Since we can prevent USB flash drives from taking away privacy on the computer, can we protect our USB flash drives as well? Of course, it is not a traditional method of writing protection buttons on a USB flash drive, but a new method. Windows XP SP2 introduces a security feature for the USB device, allowing you to add the "Write protection" function to the flash drive to prevent modification of the content in the USB flash drive.
The method is simple. In the Registry Editor, expand [HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control], and create a subitem named "storagedevicepolicies" in "control, create a New DWORD Value named "writeprotect" under this subitem and set it to 1 (hexadecimal ). Exit Registry Editor.
In this way, when someone else wants to modify the data in the USB flash drive on our computer, a warning window will pop up, informing us that the USB flash drive has been written for protection (see figure 2 ).
TIPS:
★To restore the write function of the flash disk, you only need to change the value of "write protect" to 0.
