Just to make it clear for myself - did you try running 'atacontrol
attach <channel>' after attaching the drive that wasn't attached at
boot time and it still didn't show up?

That's obvious. Since I'm planning to use this disk as a backup media,
I'll keep the FS unmounted most of the time anyway - to be protected
from 'rm -rf /' type of things.
Thanks for your input.
