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.
