+If you follow raid devel list you will soon learn that they dont 
+recommend trusting the /dev/sd* naming either as it is by
+no means static... :)
+
+depending on your hw, they may for example  hange place if you happend
+to have a usb disk plugged at boot and so on.
+
+so the thing to check is for example  what disk is mapped as 
+/dev/disk/by-id/*
+
+
+where you can match on actual disc serial number and so on...
+then you can be sure wich disk is failing / has failed...
