Is that a typo? Do you really mean "adNi"? (i.e. - ad0a, ad1c, etc?). If so, that was the original BSD naming scheme, and is probably still used on systems with disks that don't have slices. In particular, it was used for dangerously dedicated disks on FreeBSD at one point. Those disks don't have more than one slice. These days, the name adNx and adNs1x are identical (i.e. - I get the same file systems for them on either a DD or a sliced disk on -current). However, I continue using the adNx names for dangerously dedicated disks. Not only does it make logical sense, it is then obvious that they *are* DD, so you don't try tweaking the slice table.
