The FORMAT_EX_PARAMETERS structure is used in conjunction with the IOCTL_DISK_FORMAT_TRACKS_EX request to format the specified set of contiguous tracks on the disk.

Syntax

typedef struct _FORMAT_EX_PARAMETERS {
  MEDIA_TYPE MediaType;
  ULONG      StartCylinderNumber;
  ULONG      EndCylinderNumber;
  ULONG      StartHeadNumber;
  ULONG      EndHeadNumber;
  USHORT     FormatGapLength;
  USHORT     SectorsPerTrack;
  USHORT     SectorNumber[1];
} FORMAT_EX_PARAMETERS, *PFORMAT_EX_PARAMETERS;

Members

EndCylinderNumber

Indicates the number of the cylinder where the formatting should end.

StartHeadNumber

Indicates the number of the head where the formatting should begin.

EndHeadNumber

Indicates the number of the head where the formatting should end.

FormatGapLength

Indicates the length in bytes of a format gap.
