I still get the error.

The following extract from "truss gpart add -t freebsd-zfs ada2" might 
be relevant

ioctl(3,GEOM_CTL,0x1418040)			 = 0 (0x0)

Checking the relevant directories gives the following:

curlew:/root# ls -l /usr/share/nls/C
total 6
-r--r--r--  1 root  wheel  7924 26 Oct  2012 ee.cat

Checking with smartctl shows 512 bytes logical/physical
