I cannot use flushfilebuffer function because it is already opened for write access by third party software.

BOOL FlushDiskDrive(TCHAR *szDrive)
{
	BOOL bRet = FALSE;
	HANDLE h = CreateFile(szDrive, GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE,NULL,OPEN_EXISTING,0,NULL);
	if(INVALID_HANDLE_VALUE != h)
	{
		bRet = FlushFileBuffers(h);
		CloseHandle(h);
	}
	return bRet;
}
//Usage:
FlushDiskDrive(_T("\\\\.\\\\C:));
