Greetings I am trying to reuse a 500G harddrive that was previously part of an NVIDIA raid in a windows box. I have tried to clean the disk using "dd if=/dev/zero of=/dev/raid/r0 bs=1m". The dd program completed but the raid info is still on the disk, I was able to set up the disk with gpart create -s gpt /dev/raid/r0 gpart add -t freebsd-ufs -l 500Gig -b 1M newfs -U /dev/gpt/500Gig I can mount and use the disk but it still shows up at /dev/raid/r0 and my dmesg is spammed with GEOM_RAID: NVIDIA-1: Array NVIDIA-1 created. Root mount waiting for: GRAID-NVIDIA Root mount waiting for: GRAID-NVIDIA Root mount waiting for: GRAID-NVIDIA Root mount waiting for: GRAID-NVIDIA Root mount waiting for: GRAID-NVIDIA Root mount waiting for: GRAID-NVIDIA until it times out or I hit ^c uname -a FreeBSD zorro.shasta204.local 9.1-STABLE FreeBSD 9.1-STABLE #1 r246453: Thu Feb 7 11:52:20 PST 2013 root at zorro.shasta204.local:/usr/obj/usr/src/sys/GENERIC amd64 Any help greatly appreciated.

The dd program completed but the raid info is still on the disk,That's because RAID metadata is stored outside RAID itself (/dev/raid/r0), it occupies last sectors of physical disks. It can be erased with "graid delete" command, please read man graid. You need operate on its "Geom name" from "graid list | fgrep Geom" command, not on symbolic name /dev/raid/r0. You may also need -f flag (again, read man graid). Eugene Grosbein
