[snip] This sounds very familiar to something I just went through. A drive went up in smoke and the spare I pulled from the shelf had 6.2 on it. The 8 Release install would fail, something to do with either the partition table and/or labels from the earlier being invisible to the new and thus could not be written to. Boot a LiveFS CD, then at a root prompt do: sysctl kern.geom.debugflags=16 and: dd if=/dev/zero of=/dev/adx oseek=1 bs=512 count=1 where x equals your drive number. Probably should only do this before a fresh install and NOT on a system with data you want to keep. The exact error I received whilst trying to install 8 in sysinstall was this: "Unable to find device node for /dev/ad4s1b in /dev! The creation of filesystems will be aborted." Then pressing "OK" brings this: "Couldn't make filesystems properly. Aborting." -Mike
