Disable Write to USB drive Harddisk & Pendrive

Nowadays USB port & pendrive become very common. It creates security concern for large organizations that anyone can simply plug-in a pendrive or USB harddisk to steal the corporate data.

In fact there is a registry hack that can disable the read/write access to USB devices altogether. User cannot copy data to the USB disk storage, nor able to read any files and documents from the USB drive.

But, if you only want to disallow write access and allow read access, then there is another registry hack of WriteProtect in StorageDevicePolicies registry key that you can make use of. Just follow below few steps:
1) run the regedit
2) Navigate to the following registry key:


3) Create a New Key named as StorageDevicePolicies

4) Highlight StorageDevicePolicies, and then create a New DWORD (32-bit) Value named as WriteProtect

5) Double click on WriteProtect, and set its value data to 1.

I have set a ban writing to the USB memory.

Please explain how to ban all (reading and writing to the USB memory).
