I had seen that disk-suddenly-out-of-computer failure once. Coincidently enough, it was an OpenBSD system configured only for NAT, about 6 years ago. The IDE hard disk failed sometime at night. When we arrived on the next day at office. Everything was working flawlessly until someone ssh'ed to that machine. My guess is something has gone awry when the syslog went to write that new connection and suddenly the OS discovered that was no HD present. Surprisingly enough, the onboard IDE controller survived, but after installing the new disk, we found the parallel IDE cable faulty and it had to be replaced also. It was not a RAID system though... <snip>
