OEM parameters are ignored by Windows but can be used by OEM implementations. OEMs can define their own parameters with unique GUIDs. All unused Parameters fields must be described as unused by GUID_NULL in ParameterType. This structure must be preserved during exFAT formatting, except in the case of secure wipe.
