Is it possible to trick Vista into thinking it's XP so it runs programs like XP? Because I just bought a no-name 500gb portable hard drive off ebay and it won't work with vista. It just says "searching for drivers" and then says it couldn't find them. I try it on my brothers computer which has XP and it works instantly. I've tried it on other computers with XP and all of them work fine with it. Is it possible to run Vista in some sort of permanent XP compatibility mode because I hate this OS so much.
