Related to this, I can't seem to delete the disklabels from the two disks:

I've tried disklabel -D:

I've tried the suggested dd if=/dev/zero of=/dev/rsd1c bs=8k count=1 
with no success.

There's nothing on the two disks that I need so I'm just trying to wipe 
them and start over so I can merge them into a single volume.  They're 
not huge (only 2.1 GB each) but I figure 4.2 GB should be enough to 
store CVS and build the new userland?  The kernel sources are located on 
another disk right now and it seems to fit fine there.
