How to write protect your usb drive

usb drives are the most common medium for virus infections. By making your usb drive you can restrict any virus infection in your usb drive.

NOTE:- It is only useful when you do not need to write any data in your usb-dirve.

You must be logged on as the Administrator on that system.

Steps to make your drive Write Protected:
1.    Open Registry Editor by typing regedit in Run dialog.
2.    Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\
3.    Find a sub key inside it named “StorageDevicePolicies”. If it does not exist there then we need to make it. Right click on “Control” key -> New -> Key. Name it “StorageDevicePolicies” without quotes.

4.    Now right click on this newly created key and then click New -> DWORD value and name it as “WriteProtect”.

5.    Modify this key and give it a value 1.

Now save this value

and reboot your system.Now no more data can be transferred to the drive but to start using the drive again just give the “WriteProtect” key a value of 0 instead of 1 and restart the PC.
