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