Hi GEOM Developers. I'm using HP Proliant DL140G3 with Adaptec HostRAID (SATA). But I couldn't make FreeBSD 6.2-R install CD probe RAID1, so I researched DL140G3's RAID system(Software RAID). As the result, I understood that Adaptec HostRAID supports DDF format[*1]. [*1] http://www.snia.org/standards/DDFv1_00.pdf I was trying to make geom_ddf1(4), but I couldn't make it, it's too hard for me:-(. So, anyone, would you try to make geom_ddf1(4)? Of course, RAID1 support only OK! :D I have two real DDF1 data from configurated SATAs(/dev/ad4 and /dev/ad6 are RAID1 mirrored) like following way[*2][*3]. And I confirmed no configured SATAs filled all NUL(0x00) on DDF1 Anchor.

I got a result of /dev/ad4. Please see also following[*5].
