STORAGE_ENDURANCE_DATA_DESCRIPTOR structure (ntddscsi.h)

  • Article

A miniport uses STORAGE_ENDURANCE_DATA_DESCRIPTOR to report a device's endurance information to the storage port driver.

Syntax

typedef struct _STORAGE_ENDURANCE_DATA_DESCRIPTOR {
  ULONG                  Version;
  ULONG                  Size;
  STORAGE_ENDURANCE_INFO EnduranceInfo;
} STORAGE_ENDURANCE_DATA_DESCRIPTOR, *PSTORAGE_ENDURANCE_DATA_DESCRIPTOR;

Members

Version

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

Size

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

EnduranceInfo

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

Remarks

The miniport returns this structure when handling an IOCTL_SCSI_MINIPORT request that has an SRB_IO_CONTROL structure with a Signature of IOCTL_MINIPORT_SIGNATURE_ENDURANCE_INFO, and a ControlCode of IOCTL_STORAGE_QUERY_PROPERTY with a PropertyId of StorageDeviceEnduranceProperty and a QueryType of PropertyStandardQuery.

The storage port driver uses STORAGE_HW_ENDURANCE_DATA_DESCRIPTOR, which is defined in ntddstor.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.
