FORMAT_PARAMETERS

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, *PFORMAT_PARAMETERS;
