Duplicate content indexed. Mod re-write and the robots.txt file. Safe?

It would be better to find out *why* you're getting those "raw" URLs indexed, and to put a stop to it first.

Then 301-redirect any direct client requests only from the "raw" to the friendly URLs. I emphasized that phrase because it's important: You'll need to look at the client HTTP request server variable to be able to distiguish between a raw URL request received from a client (browser or 'bot) and a raw URL request resulting from your existing raw-to-friendly-URL internal rewrite.

But first, make sure you have no links on your site to these raw URLs, and try to get any such links from other Web sites that link to your site corrected before proceeding.
