Faulty Disk Drive

Hi,

I've got a Dl 160 Proliant G5 and I can see on the fron that there is a disk drive failure as it has a red light.  It's running Windows 2008 R2, but when I look on the drivers to download I can't find any software to diagnose where the problem is.

I download and installed the Array Diagnostics and SMartSSD utility but it told me that I dont have a smart array controller, just and LSI Adapter, SAS 300 series.

Is there any software out there that can diagnose my hardware issues?

Thanks
