CLUSPROP_DISK_SIGNATURE structure

Describes the signature that is stored on the disk for identifying it to the operating system. The CLUSPROP_DISK_SIGNATURE structure is used as an entry in a value list and consists of:

• A CLUSPROP_VALUE structure describing the format, type, and length of the numeric data.
• A DWORD value.

For convenience, the CLUSPROP_VALUE members are listed explicitly:

Syntax

typedef struct _CLUSPROP_DISK_SIGNATURE {
  CLUSPROP_SYNTAX Syntax;
  DWORD           cbLength;
  DWORD           dw;
} CLUSPROP_DISK_SIGNATURE, *PCLUSPROP_DISK_SIGNATURE;

Members

• Syntax
  Member of the CLUSPROP_VALUE structure with a value of CLUSPROP_SYNTAX_DISK_SIGNATURE (0x00050002).

• cbLength
  Member of the CLUSPROP_VALUE structure indicating the count of bytes in the dw member.

• dw
  Numeric value that describes the disk signature. This value can be retrieved from the Signature member of the DRIVE_LAYOUT_INFORMATION_MBR structure in the Mbr member of the DRIVE_LAYOUT_INFORMATION_EX structure returned from the IOCTL_DISK_GET_DRIVE_LAYOUT_EX control code.
