The Do not allow non-Enhanced Storage removable devices machine setting should be configured correctly. This policy setting configures whether or not non-Enhanced Storage removable devices are allowed on your computer. If you enable this policy setting, non-Enhanced Storage removable devices are not allowed on your computer. If you disable or do not configure this policy setting, non-Enhanced Storage removable devices are allowed on your computer. Fix: (1) GPO: Computer Configuration\Administrative Templates\System\Enhanced Storage Access\Do not allow non-Enhanced Storage removable devices (2) KEY: HKLM\Software\Policies\Microsoft\Windows\EnhancedStorageDevices\DisallowLegacyDiskDevices
