2.2.4.19 NTMS_MEDIATYPEINFORMATION Structure

The NTMS_MEDIATYPEINFORMATION structure defines the properties specific to a type of media supported by RSM.

 typedef struct _NTMS_MEDIATYPEINFORMATION {
   DWORD MediaType;
   DWORD NumberOfSides;
   DWORD ReadWriteCharacteristics;
   DWORD DeviceType;
 } NTMS_MEDIATYPEINFORMATION;

MediaType: Each disk or tape driver reports the media type enumeration value of the medium that is currently mounted in the drive. This media type value MUST be unique, and is mapped to a human-readable string in the object szName member of a NTMS_OBJECTINFORMATIONA or NTMS_OBJECTINFORMATIONW structure.
