IOCTL_STORAGE_GET_MEDIA_TYPES IOCTL (winioctl.h)

Retrieves the geometry information for the device.

To perform this operation, call the DeviceIoControl function with the following parameters.

BOOL DeviceIoControl(
  (HANDLE) hDevice,                 // handle to device
  IOCTL_STORAGE_GET_MEDIA_TYPES,    // dwIoControlCode
  NULL,                             // lpInBuffer
  0,                                // nInBufferSize
  (LPVOID) lpOutBuffer,             // output buffer
  (DWORD) nOutBufferSize,           // size of output buffer
  (LPDWORD) lpBytesReturned,        // number of bytes returned
  (LPOVERLAPPED) lpOverlapped       // OVERLAPPED structure
);

Remarks

This device I/O control operation is for all class drivers, as well as non-SCSI hard drives and floppy disk devices.
