Thanks.  According to the newfs(8) man page it is used only for BSD

 I am okay with the FAT16 formatted
SD card, I'm just upset that I paid for a 2.0 GB card and ended up with
what seems to be a 1.0 GB card.  I would be happy if I could make the
SD card look like this:

  slice 1  2.0 GB (well, 1920 MB if you insist)
  slice 2  <UNUSED>
  slice 3  <UNUSED>
  slice 4  <UNUSED>

It's generally not useful to slice/partition a small SD card. Without a slice table, the whole device is just one slice.

Offhand I don't know if you can overwrite an existing slice table (boot block) with just a 'newfs_msdos /dev/da1'. Probably.

If not, you can just 'dd if=/dev/zero of=/dev/da1 bs=512 cnt=1' and then do the newfs_msdos.

If you plan to use that card in a camera, you are a little safer doing a "full" or "low-level" format with the card in the camera. Some cameras create and like not-quite-right filesystems. Older Canon cameras, for instance.

Finally, there are more than a few reports of SD cards with false capacities bought on ebay.
