_FORMAT_EX_PARAMETERS structure

Description

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.

Members

MediaType

Indicates format information, such as the disk size and the number of bytes per sector. For a list of the values that can be assigned to this member, see MEDIA_TYPE.

StartCylinderNumber

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

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.

SectorsPerTrack

Indicates the number of sectors per track.

SectorNumber

Contains an array whose first element indicates the number of the sector where the formatting should begin.
