External USB Disks becoming Write Protected

We backup up client servers to external USB hard disks.  We keep having these disks come up to be Write-Protected.  We cannot figure why or even how to keep them from doing this.  It seems to be on Windows Server 2012 R2 and also Windows Server 2016.  Does anyone know how to fix this and keep it from happening.  We have looked on the web and found a few solutions about looking in StorageDevicePolicies in the registry but we do not have that setting in the server Registry.  Any help or solution would be much appreciated.

You can remove write protection from your usb flash drive using the below method:

a. Open start menu, in the search bar type regedit and press enter. This wil open the registry editor.

b. Navigate to the following path:


 If the registry key StorageDevicePolicies does not exist, you will need to create it manually.
 c. Highlight StorageDevicePolicies, and then create a New DWORD (32-bit) Value named as WriteProtect.
 d. Double click the key WriteProtect in the right window and set the value to 0 in the Value
 Data Box and press OK button
 e. Restart your computer and try copying files into your USB drives.

Thierry - I already said that I do not have the StorageDevicePolicies key at all.  So, I would be creating the container and the key.  No article at all said to do that.

That's why I highlighted the "If the registry key StorageDevicePolicies does not exist, you will need to create it manually"
