I have this problem quite often in my version - 5.1-Release #9. The trick is to never reboot. The bad superblock is always found on my second partition, mounted on /disc2 (of which I use half a gig as swap space, the other 5.5gigs do absolutely nowt) Sorry. Let's cut to the chase. Type "newfs /dev/da0s1a" and you should get back on the ball fairly quickly. John --
