Connection type is pure SATA, without= convertors. I've created misaligned 10G-partition: kibab-desktop# gpart create -s GPT ad7 ad7 created kibab-desktop# gpart add -t freebsd-ufs -s 10G ad7 ad7p1 added kibab-desktop# gpart show ad7 =3D> 34 2930277101 ad7 GPT (1.4T) 34 20971520 1 freebsd-ufs (10G) 20971554 2909305581 - free - (1.4T) Right now I'm running phybs -w /dev/ad7p1 Please write me what additional tests should I conduct.
