You don't have to buy a WD Scorpio; any 2.5'' will do. I replaced my 320 gig with a Fujitsu 1TB which I have maxed in 3 months. I can't speak highly enough of the MS Data transfer cable though, all one has to do is swap the internal with the new one, attach it to the cable and on to the XBOX USB, and voila! Like magic everything can be copied over to the new internal.

Also, you can always access your FSD from your comp using WEBUI. Just type in the IP address your router assigns to your XBOX (visible on the bottom left hand side of FSD by clicking RS), enter the default password (get it from the release notes for your corresponding FSD version), navigate to your chosen game with the unwanted box art, download your desired cover from the net after doing a google search, browse to this file in the drop down dialog box under the unwanted full cover art, and click update at the bottom. Simple!
