Plugged back in, on different cables, they are incomunicado. Smartctl
sees them, and hangs the system boot when it gets no response. Only way
to boot is to powerdown and remove them, them the raid10 is found and the
rest of the boot is fine.
And I am beginning to think in terms of a mobo problem, the bios is only
seeing the cpu bus a .9 something volts, and the cpu fan at 721 rpm, but
nothing else and gkrellm isn't even seeing any of that.
