FreeBSD 10.2 + mate-desktop environment
Create 1 slice covering the entire disk: # fdisk -I /dev/devN
Create 1 partition covering the entire slice: # bsdlabel -w devNs1
Create a filesystem on the "a" partition (soft-updates enabled): # newfs -U /dev/devNs1a
After this, mate can auto-mount the usb device, and I have no idea why gpart will not work here...
