How To Enable Write Protect Your Usb Flash Drive

 

To enable write protect on a usb which does not have write-protect feature follow these steps.

1. Open the Registry Editor (Open the “Run” dialog box, type regedit and hit “Enter”).

2. Navigate to the following Registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\

3. Now right-click on Control, and click on New>Key 

4.Now rename this new key to StorageDevicePolicies..

5 Now right-click on StorageDevicePolicies and create a New>DWORD (32-bit) Value 

6 Now rename this value to WriteProtect

7 Double-click on WriteProtect and set the Value data to 1.

Now the right-protection for USB drives is enabled on your computer (no restart required) and thus it would not be possible for anyone or any program to add/delete the contents from your USB flash drive. Any attempt to copy or download the files onto the USB drive will result in the following error message being displayed.

USB-Write Protect Error

To revert and remove the write-protection, all you need to do is just change the value data for write-protect (Step-5) from 1 back to 0. Now write access to all the USB devices is re-enabled.
