Hi, Thank you for help. I provide you the maximum information about my partitio= ns. Before, I watch the kernel configuration. When I fetch the kernel sources, I can see 2 differents configuration files : DEFAULTS and GENERIC. and the line : "options GEOM_PART_GPT" is present only in GENERIC. If I use my knowledge in linux systems, I would say that my actual kernel was compiled with the DEFAULTS conf, which doesn't enable the support of GPT for GEOM. Maybe I'm wrong, my knew kernel is compiling... On Freebsd : [Dante@iris-bsd /usr/home/Dante]$ ls /dev/|grep ^ad ad0 ad0s2 ad0s3 ad0s4 ad0s4a ad0s4b ad0s4c my dmesg : http://pastebin.com/m7b5f130e On Gentoo : dante@iris:~ % LANG=3DC sudo parted /dev/sda GNU Parted 1.8.8 Using /dev/sda Welcome to GNU Parted!

UFS is not recognize on my gentoo system. The partition 7 is my home, the one that I want to mount under freebsd.
