What do you see in your server logs? Does googlebot fetch those pages?
As netmeg writes above: if you disallow crawling of all pages in robots.txt then googlebot never will try to fetch the pages, and thus never will see the 410. You need to remove the disallow in robots.txt so it can fetch the pages and then it will see the 410 status code.
