Finding Unread Threads from before mark as read date

I am admin to a forum that I had to take down for a couple of months for personal reasons. I've just put it back up but all the unread posts are no longer displayed, presumably because they are too old.
The trouble is, I kbow some of those were pretty important for me to read and I don't want to have to wade through everything to try and find them!
Is there a way to interrogate the db or something to find out which threads have posts I have never visited? I'm talking 20-30 posts so I don't mind *too* much if its a manual process.

That data won't have been maintained. The read tracking data is only kept for as long as the "Read Marking Data Lifetime" option specifies (30 days by default).
