NTMS_PARTITIONINFORMATION Structure

  • Artigo

[Removable Storage Manager is no longer available as of Windows 7 and Windows Server 2008 R2.]

The NTMS_PARTITIONINFORMATION structure defines the properties specific to the side object.

Syntax

typedef struct _NTMS_PARTITIONINFORMATION {
  NTMS_GUID     PhysicalMedia;
  NTMS_GUID     LogicalMedia;
  DWORD         State;
  WORD          Side;
  DWORD         dwOmidLabelIdLength;
  BYTE          OmidLabelId[NTMS_OMIDLABELID_LENGTH];
  TCHAR         szOmidLabelType[NTMS_OMIDLABELTYPE_LENGTH];
  TCHAR         szOmidLabelInfo[NTMS_OMIDLABELINFO_LENGTH];
  DWORD         dwMountCount;
  DWORD         dwAllocateCount;
  LARGE_INTEGER Capacity;
} NTMS_PARTITIONINFORMATION;

Members

  • PhysicalMedia
    Unique physical media identifier for the medium that contains this side.

  • LogicalMedia
    Unique logical media identifier (LMID) for a piece of logical media that contains this side. This parameter is a NULL if the side is not allocated.

  • State
    Side life cycle information. This can be one of the following values.

    Value Meaning
    NTMS_PARTSTATE_ALLOCATED

    The media has been allocated to an application.
    NTMS_PARTSTATE_AVAILABLE

    The media is available to be allocated.
    NTMS_PARTSTATE_COMPLETE

    The media has been completely written and marked as complete by an application.
    NTMS_PARTSTATE_DECOMMISIONED

    The media is unsuitable for data storage and is no longer usable.
    NTMS_PARTSTATE_INCOMPATIBLE

    The media has been found to be and marked as incompatible with the drive.
    NTMS_PARTSTATE_FOREIGN

    The media is in a unrecognized pool.
    NTMS_PARTSTATE_IMPORT

    The media is in the import pool.
    NTMS_PARTSTATE_UNPREPARED

    The media is waiting for a free label to be applied.
    NTMS_PARTSTATE_RESERVED

    The side has been reserved by the AllocateNtmsMedia function with the dwOption parameter set to NTMS_ALLOCATE_NEW.

     

  • Side
    Zero-relative value which indicates which side of a multi-sided media this is. For single-sided media, such as tape, this value is always zero. For dual-sided media one NTMS_PARITIONINFORMATION record has this property set to zero - the "A" side - and a second NTMS_PARTITIONINFORMATION record has it set to 1 - the "B" side.

  • dwOmidLabelIdLength
    Length of the label ID string of the on-media identifier.

  • OmidLabelId
    Label ID unique identifier of the on-media identifier.

  • szOmidLabelType
    Label type of the on-media identifier.

  • szOmidLabelInfo
    Label information of the on-media identifier.

  • dwMountCount
    Number of times this media has been mounted into a drive. This is initialized to zero when the objects are created in the database.

  • dwAllocateCount
    Number of times this media has been allocated.

  • Capacity
    Number bytes of storage available on this side.

The NTMS_PARTITIONINFORMATION structure is included in the NTMS_OBJECTINFORMATION structure.
