The Windows operating system has a Registry setting that can add USB write protection to a computer system. It is like a switch that can be enabled to make use of the write protection or disabled to allow write processes.

Users who experience problems writing to USB devices might want to take a look at this setting as well if they have the proper rights to do so to see if it is the cause for their difficulties.

Start by opening the run dialog box with the keyboard shortcut [Windows R]. Type [regedit] and hit [enter]. This should open the Windows Registry editor.

Navigate to the following Registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\

Look at the sub-keys and see if a key named StorageDevicePolicies is listed. If it is skip this paragraph and read the next. If it is not create the key by right-clicking Control and selecting New > Key

See if there is an entry named WriteProtect. It can be easily created if it is not present by right-clicking in the right window and selecting New > DWord from the menu. The following values are allowed for this entry:

• 0 – This will allow write processes on USB Flash Drives
• 1- This will block write processes on USB Flash Drives.

An alternative would be to delete the Registry key WriteProtect completely to enable both read and write processes. A restart or log off is required before the changes take effect.

What I did was to create a main folder on my E: drive which I named USB. I then assigned all my USB devices to subfolders of that folder which led to less confusion on my part. (Create the subfolders before continuing). Here is what I did after creating the folder structure.

Press Windows R, enter diskmgmt.msc and hit enter. This opens the Disk Management configuration that should display all drives and devices currently connected to your computer. Pick an USB device from the list and right-click that entry. Select Change Drive Letter and Paths from the menu.

This should open a new window that is displaying the current drive letter of the device and three buttons at the bottom which are named Add, Change and Remove.

Click on the Add button, select Mount into the following empty NTFS folder and click on browse. Now navigate to the subfolder that you want to assign the usb drive to and confirm the assignment. The USB drive will from now on be accessible from that folder as well if it is connected to the computer.

You can remove the drive letter if you want that by marking it in the main window and clicking on Remove.
