You know what, after googling for serveral hours, I found out that it did not let me write on the disk because the kernel had SECURELEVEL=2. This is something that should be in the manual. I appreciate that you wanted to help me, but actually you pointed me to the wrong direction two times. I suggest to change the documentation of the disklabel/bsdlabel and fdisk programs. We should add this warning: "Warning: you need to disable your kernel securelevel in /etc/rc.conf. The kernel does not allow to modify disk label information above securelevel=N." (I'm still not sure about the value of N). I'm not sure where can I add this request to change the documentation. But it would save hundreds of hours for newbies and supporters too. Best, Les
