STORAGE_DEVICE_UNIQUE_IDENTIFIER structure (storduid.h)
The STORAGE_DEVICE_UNIQUE_IDENTIFIER structure defines a device unique identifier (DUID).
Syntax
typedef struct _STORAGE_DEVICE_UNIQUE_IDENTIFIER {
ULONG Version;
ULONG Size;
ULONG StorageDeviceIdOffset;
ULONG StorageDeviceOffset;
ULONG DriveLayoutSignatureOffset;
} STORAGE_DEVICE_UNIQUE_IDENTIFIER, *PSTORAGE_DEVICE_UNIQUE_IDENTIFIER;
Members
Version
The version of the DUID.
Size
The size, in bytes, of the identifier header and the identifiers (IDs) that follow the header.
StorageDeviceIdOffset
The offset, in bytes, from the beginning of the header to the device ID descriptor (STORAGE_DEVICE_ID_DESCRIPTOR). The device ID descriptor contains the IDs that are extracted from page 0x83 of the device's vital product data (VPD).
StorageDeviceOffset
The offset, in bytes, from the beginning of the header to the device descriptor (STORAGE_DEVICE_DESCRIPTOR). The device descriptor contains IDs that are extracted from non-VPD inquiry data.
DriveLayoutSignatureOffset
The offset, in bytes, to the drive layout signature (STORAGE_DEVICE_LAYOUT_SIGNATURE).
