yes and i can't change it. Because it isn't selectable. If you move with 
the cursor up and down you can't mark partition c

Hm I can't say if this disk had a NetBSD label before, but I think 
because it is my old HP715/50 disk, there was Linux or HP-UX installed.
I tried CURRENT from 2006-06-08 and it worked for me.
