VOLUME_PHYSICAL_OFFSET structure (ntddvol.h)
The VOLUME_PHYSICAL_OFFSET structure contains a physical offset into a volume and its accompanying physical disk number and is used with IOCTL_VOLUME_PHYSICAL_TO_LOGICAL and IOCTL_VOLUME_LOGICAL_TO_PHYSICAL to request a logical offset equivalent of a physical offset or a physical offset equivalent of a logical offset, respectively.
Syntax
typedef struct _VOLUME_PHYSICAL_OFFSET {
ULONG DiskNumber;
LONGLONG Offset;
} VOLUME_PHYSICAL_OFFSET, *PVOLUME_PHYSICAL_OFFSET;
Members
DiskNumber
Contains the number of the physical disk.
Offset
Contains the physical offset in bytes of the data on the disk.
