You're trying to create a 460gb file system on a 80gb drive.

When newfs reaches the drive's boundary and attempts to write to the
next sector, it tries to divide by 0 and gets slapped back 9000 years in
time by Chuck Norris.



Try this:
gpart delete -i 1
gpart create -s 78g -i 1 -t freebsd-ufs /dev/ad1

Then try to newfs -U it.
