Click Start ->> Run -<< type "regedit" and click "OK" ->> open the HKEY_LOCAL_MACHINE and expand "System" ->> check if there is a "Storage Device Policies" under ControlSet002\Control\ and ControlSet001\Control. If you can find the "Storage Device Policies" and see the write protection, you should change the number in the "DWORD value" box into "0" and press "OK". If you can find the "Storage Device Policies", you should follow these steps: HKEY_LOCAL_MACHINE ->> SYSTEM ->> CurrentControlSet ->> right click on "Control" and create a new key ->> rename the new key as "Storage Device Policies" ->> create a new "DWORD value" and rename it as Write Protect and set the number as 0.
