You obviously did not really partition the slice with bsdlabel. The c
partition is invalid for a filesystem. If you look at the label I'm sure
you'll see that the FSTYPE field is 'unused', with a comment that reads
``"raw" part, don't edit``. You should add a partition with bsdlabel,
perhaps partition 'a', with fstype 4.2BSD. You can then newfs this
partition.
