The FORMAT_PARAMETERS structure provides information used in formatting a contiguous set of disk tracks.
typedef struct _FORMAT_PARAMETERS{ MEDIA_TYPE MediaType; DWORD StartCylinderNumber; DWORD EndCylinderNumber; DWORD StartHeadNumber; DWORD EndHeadNumber; } FORMAT_PARAMETERS ;
The DeviceIoControl function uses a FORMAT_PARAMETERS structure as input to an IOCTL_DISK_FORMAT_TRACKS device I/O operation.
