I supervise the use of a 'community' desktop computer. I would like to allow the use of the desktop via an external drive to a specific individual.

How do I secure the internal hard drive so that no access is possible while using the external drive? Primarily I want to avoid accidental modification of the hard drive.

The desktop runs Vista. The external is Ubuntu.
