When the router detects an error with one of the drives, it will remove 
it from the boot list (a custom juniper bios setting). This keeps the OS 
from even seeing the drive the next time it boots, so a bad drive can't 
cause the router to stall or crash. This is probably what happened in 
your case, since ad1 isn't in your boot list.

If you want to readd it (to see if its actually broken), drop to shell, 
su to root, and do:

sysctl -w machdep.bootdevs=whatever

i.e. take your current bootdevs and add "disk" (the ad1), or whatever
you want to do.
