KaFu Posted February 20, 2012 Share Posted February 20, 2012 On Vista+ Admin rights might be necessary.MSDN: CreateFile function"dwDesiredAccess [in]If this parameter is zero, the application can query certain metadata such as file, directory, or device attributes without accessing that file or device, even if GENERIC_READ access would have been denied.""Physical Disks and VolumesDirect access to the disk or to a volume is restricted. For more information, see "Changes to the file system and to the storage stack to restrict direct disk access and direct volume access in Windows Vista and in Windows Server 2008" in the Help and Support Knowledge Base at http://support.microsoft.com/kb/942448."So querying device attributes with dwDesiredAccess = 0 will work without admin rights, whereas access to the content will require admin rights.
