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.
