I find it rather confusing in my log, and there are situation when you hotplug the disk which does not make it show up right after the ataX line, also if the logs overflow, then you can't know anyway. (I know there's syslog too) There doesn't seem to be any mapping in /sys I though lshw would show it but it isn't.
