it will be printed in the terminal, you may use an editor otherwise
But if you don't really want to mount the other partitions, it's an issue of KDE-sudo, or another KDE-component. You'll have to search in the KDE-systemsettings. Anywhere in a section like "advanced usersettings", I don't have the english menus available yet, I'll have to check it with another user. It has to do with "automatically mounting of plugable devices". I'll look it up and add a screenshot.
