(2850) Defining which drive in array is bad?

Hello Family,

Thanks for the chance to post this here...

I have a 2850 running a RAID-5 array and we are looking to change out 
the drive that may be causing the following "unreferenced_inode" error,
and I'm not so sure there is a bad drive -- not sure which of the
five(5) w/1-hotspare, has caused this error anyway.

Is there a way I could pinpoint the physical drive with any utility?

TIA
