DroboElite / B800i Single Drive Health Check

Hi All,

I recently upgraded all of the drives in my B800i from 4TB to 6TB one by one and letting the array reallocate the data around. My write speed to the array has dropped significantly and I can hear one of the drives occasionally click. Knowing that it will eventually fail I want to try to investigate which drive in the array it is. On my 5D you can select each drive and in the dashboard and check the health. There is no way to do that in the Drobo dashboard for the B800i and DroboElite. Is there another way I can check to see which drive might have errors instead of laying on the floor hoping to pinpoint which of the 8 is making the click noise at sporadic times?
