Eak!! Error, no posts at all!

Hiya, just checked my blog today and recieved this error at the top of the page

WordPress database error: [Got error 28 from storage engine]
SELECT DISTINCT * FROM wp_posts WHERE 1=1 AND post_date_gmt <= ‘2005-06-20 06:53:59’ AND (post_status = “publish” OR post_author = 1 AND post_status != ‘draft’ AND post_status != ‘static’) GROUP BY wp_posts.ID ORDER BY post_date DESC LIMIT 0, 15

I have not touched anything at all, and not changed anything for weeks now.

My blog is at
