Shadowing Problem

Hey

We had a look at our server today(running Small Business Server 2000) and discovered that our drives havn’t been shadowing for a while. We use a Raid 0 80gb drive partitioned 30gb/50gb that is shadowed onto a 120gb partitioned 50gb/70gb. Have looked at shadowing config on boot and arrays appear to be setup right,

Any tips? Advice? Is there anything we should check? Any help would be greatly appreciated…
