gpart(8) doesn't enumerate disks without any supported partition scheme 
present.
You can create new partition schemes with the help of gpart(8), but it's 
imho correct not to show them, because 'gpart show' is meant to give 
information about (existing) partition schemes - no scheme no info; thus 
your vanilla disk is "unknown" to gpart(8).

I remember that I always thought the geom(8) disk class is kind of 
hidden - especially since the man page misses listing DISK in the
"Currently available classes which are aware of geom(8)" section!

The "show" command was enriched to contain valuable details, such as NAA.
So 'geom disk' turned into one of the most useful mass storage admin 
commands. imho.
Maybe somebody should correct the aforementioned man page section and 
add add any hint in the SEE ALSO section, because there is no gdisk(8) 
aequivalent, like for all other geom classes...

P.S. Put it on my loger-term todo to file a bug report with a proposed 
man page diff...
