Why are you putting in an absolute directory reference? Apache is not going to understand that. You should be going back to the root of your webserver, and no further up than that. (Your root is "/htdocs")

It appears in your case your dirroot should be "/moodle", and I don't think you should set up your file structure so that you have to go up higher than htdocs. In other words, you need to store your moodledata directory below htdocs, not above or alongside it.
