disk/disklabel oddity

I just installed a new disk in a machine, intending to make it the new root. I
used fdisk and disklabel -r -I to set up the partitions, all of which seemed to
work fine.

When I try to newfs, I get

wtfs: write error for sector 16: Read-only file system

Based on googling around, I'm guessing that this cryptic message is trying to
tell me I've screwed up the allocations somewhere, but I can't see the fault.

I'm a little concerned that the disklabel output indicates that the label is
fictitious. That *must* be a clue, but I don't get it... also, newfs outputs the
super-block backups *very* quickly.

Help?

Thanks,
chris

One more oddity: I tried using wd1c to build the fs, just for grins, and get:

yertle: {1} newfs -b 64k -f 16k /dev/wd1c
newfs: /dev/wd1c: open for read: Device not configured

WTF?

Something wrong with the label, but what?
