MediaIntegrityCheck

Clear message

Summary

As of Ubuntu 5.10, the installation and live media are capable of performing an integrity check, but they do not do so by default, and the means to activate it is not obvious. We should consider whether it is worth the additional time to perform the check by default (this should be considered in light of anticipated support for DMA on CD-ROM devices), or whether we can provide a more obvious path to the functionality.

Rationale

Bad CDs happen, and we need a way to detect them. The way to do so should be obvious to the user.

Use cases and scope

  • Matt is installing Ubuntu, but receives strange error messages about read errors. His copy of Ubuntu is from a friend, so he figures out that the media might be defect and so he wants to verify that his media is in working condition.

Design

  • The media integrity check option should be made way more visible. This is achieved through the use of a newer syslinux which gives us a usable menu as well as possible changes to cdrom-checker to make it be able to run without the main menu.

Implementation

  • Get newer version of syslinux into the installer
  • Add menu item choice for "Media integrity check", which in turn starts cdrom-checker instead of main-menu as the menu. cdrom-checker should notify the user about success/failure and then reboot.
