the topic stills shows up just as much when you scan through the new posts like i do or if people have subscibed to it.
Would be good if you found a way round it as i have a HDD sat around which is exactly the same- not as much data but just as annoying!

mine has lots of my first born on it(pics and videos), got a big patch of 6months of her life missing and if you don't update your thread i may never get them back
