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.
