The permissions on this file do not prevent anyone from reading or changing the temporary file's contents while Rdisk is running. When the Rdisk tool completes the update procedure, the temporary file is deleted. However, if the Rdisk tool is interrupted or ends abnormally (requiring a restart), the file may still be accessed after the computer is rebooted. The file can also be read while the Rdisk tool is running.
