How To Enable Device Media Write Protection In USB Flash Drives, Pen Drives
In my previous post, I wrote about a registry hack to enable or disable access to USB Removable Mass Storage Device, Pen Drive, thumb and portable hard drive in Windows. When this hack is activated, you’ll neither be able to transfer any data from the computer nor copy any data to the computer from any USB storage mediums.
In this article we’ll see how we can enable write protection on external storage drives/devices, which means users will be able to copy data from external sources but not write date to external storage devices. This feature, where in the administrator disables the write access to external storage device is known as WriteProtect. This will ensure no private data leaves the PC without administrators permission.

Here’s how you can enable write protection to USB Removable mass storage devices, pen drives, thumb drives and portable drives.
1> Click on “Start –> Run –> type regedit and hit Enter”
2> Navigate to “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control”
3> Create a new key and name it as StorageDevicePolicies
4> Select StorageDevicePolicies and create a new DWORD (32-bit) Value and name it as WriteProtect.
5> Set the value of WriteProtect to 1, this can be done by double clicking on WriteProtect.
Close registry editor and you are done. Sometimes you may have to boot the machine before the changes takes place. After WriteProtect is activated, users won’t be able to write any data from computer to any external storage device.
If anyone tries to write data to external storage device, then they’ll encounter any one of these messages :
The disk is write protected.
The media is write-protected.
Remove the write protection or use another disk.
