The disk needs to have at least one partition that's marked as active, if I remember correctly. This is the "old way" of initializing it: # fdisk -BI /dev/ada1 # bsdlabel -B -w ada0s1 Add "-b /boot/boot0" for the fdisk command if you need to specify the boot code (normal boot or boot manager). If you want to use the whole disk as a "dedicated partition", you can do this: # bsdlabel -w ada1 # bsdlabel -e ada1 set type "4.2BSD" for 'a' partition make 'a' same size as 'c' save # newfs -m 0 -i 16384 -b 16384 -f 2048 -U -t enable -n disable -L ssdroot = /dev/ada1a # bsdlabel -B ada1 Adjust -i, -b and -f according to the expected usage. But that's not a very kind way to deal with disks. :-) You should use gpart today. There is good documentation in "man gpart", as well as those resources: http://www.wonkity.com/~wblock/docs/html/disksetup.html https://www.freebsd.org/doc/handbook/disks-adding.html http://www.freebsd.org/doc/handbook/geom-glabel.html Avoid MBR partitioning if possible - it's considered obsolete, outdated, old-fashioned, stupid and lame. ;-) --=20 Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
