STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR structure (ntddstor.h)

A storage port driver uses the STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR structure to report a device's endurance information.

Syntax

typedef struct _STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR {
  ULONG                     Version;
  ULONG                     Size;
  STORAGE_HW_ENDURANCE_INFO EnduranceInfo;
} STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR, *PSTORAGE_HW_ENDURANCE_DATA_DESCRIPTOR;

Members

Version

Version of this structure. Set this to be sizeof(STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR).

Size

Size, in bytes, of the buffer containing the endurance information. Set this to be sizeof(STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR).

EnduranceInfo

A STORAGE_HW_ENDURANCE_INFO structure in which to store the device's endurance information.

Remarks

A storage port driver uses this structure when communicating with its miniport for an IOCTL_SCSI_MINIPORT request that has an SRB_IO_CONTROL structure with a Signature of IOCTL_MINIPORT_SIGNATURE_ENDURANCE_INFO, and a ControlCode ofIOCTL_STORAGE_QUERY_PROPERTY with a PropertyId of StorageDeviceEnduranceProperty and a QueryType of PropertyStandardQuery.

The miniport uses STORAGE_ENDURANCE_DATA_DESCRIPTOR, which is defined in ntddscsi.h. STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR and STORAGE_ENDURANCE_DATA_DESCRIPTOR are identical in size, so the storage port driver and miniport should cast the structure they receive accordingly when communicating with each other.
