I use FltGetVolumeFromName in a minifilter port message callback but it returns a STATUS_ACCESS_DENIED status.
In msdn docs: http://msdn.microsoft.com/en-us/library/ff543220(v=VS.85).aspx
it says that “The caller must have FILE_READ_DATA access to the volume.”
How can I make my caller have FILE_READ_DATA access rights on the volume?
