Hmm.  That's odd if you're certain that the new drive is on the cable
to the primary controller.  I'd be interested in how the BIOS reports
the drives during POST (power-on self test, i.e. boot).

I also wonder why it lists /dev/hdd5 as unknown.  What is your root
partition?

But if "linux rescue" mounts it without carps, I'd run "mount" or "df"
before doing the chroot, to see what is where.
