Well this is definately a Hardrive Error.....For error 7 the only fix would be to push the IDE cable into the HD and make sure its connected good, if that do fix it then your HD is giving out on ya which it sounds like hence the "clickbuzz" sound...try what i said if that dont work get your eeprom off of your HD and onto your PC and follow this tutorial to upgrade/replace your broken HD... http://forums.afterdawn.com/thread_view.cfm/1/203286 Upgrading HD on Softmodded Xbox Tutorial
I think you tried modding your Halo 2 Maps and did them wrong. Or you screwed with your HD a little and now there is an interference between the Disc and the HD H2 Memory.
Evilmodda has a good point......if what i said dont work because you dont have your eeprom you can try and hotswap http://my.afterdawn.com/thereturn/blog_entry.cfm/374/hotswap
