I have 4 internal disks. One is a raptor. It is loud and starting to make me want to smash my computer from the NOISE. I have menumeters running with the disk activity monitor, as well as the istat widget. But neither of these shows me WHICH disk is running out of control. I'd like to know when my Mac Pro starts to beachball and the hard drives are going crazy making noise, which drive exactly is doing all the churning. Right now, all it shows me is a amalgamation of all 4 internal drives on menumeters/istat, but there's no way to know which drives of the 4 are churning, and which aren't. Does anyone know how I can do this? Menumeters, istat, or activity monitor; none of these do it.
