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?

I'll keep the FS unmounted most of the time anyway - to be protected 
from 'rm -rf /' type of things.

Thanks for your input.
