You should replace it with a disk identical to Device #3, a Seagate ST373207LC. Once it's replaced it should automatically rebuild its self from Device #3 under control of the Adaptec 2120S controller I reckon. I'm only familiar with HP SmartArray controllers. If you're able to get the config info you've posted the system is obviously up.
See how you get on after replacing it.
