15.4. Verifying Media

The DVD offers an option to verify the integrity of the media. Recording errors sometimes occur while producing DVD media. An error in the data for package chosen in the installation program can cause the installation to abort. To minimize the chances of data errors affecting the installation, verify the media before installing.
If the verification succeeds, the installation process proceeds normally. If the process fails, create a new DVD using the ISO image you downloaded earlier.
