The DISK_GEOMETRY structure describes the geometry of disk devices and media.
typedef struct _DISK_GEOMETRY { LARGE_INTEGER Cylinders; MEDIA_TYPE MediaType; DWORD TracksPerCylinder; DWORD SectorsPerTrack; DWORD BytesPerSector; } DISK_GEOMETRY ;
The DeviceIoControl function receives a DISK_GEOMETRY structure in response to an IOCTL_DISK_GET_DRIVE_GEOMETRY device input and output contol (IOCTL) operation. The DeviceIoControl function receives an array of DISK_GEOMETRY structures in response to an IOCTL_DISK_GET_MEDIA_TYPES device I/O operation.
DeviceIoControl, IOCTL_DISK_GET_DRIVE_GEOMETRY, IOCTL_DISK_GET_MEDIA_TYPES, MEDIA_TYPE
