I have installed a second hard drive (500GB Western Digital SATA SE16) in my Mac Pro quad-core. The drive spins down regardless of the power management settings (system preferences) and does so even when I’m actively working, but not directly accessing the second drive. It then spins up, with a corresponding time lag of 10-20 seconds and the spinning beach ball, when drive access is necessary. I know from the WD website that there is a setting for a jumper on pins 3 & 4 which will prevent spin down (much like would be required for a RAID setup). Does it make sense to enable that jumper to prevent spin down in this case? Will the system power management settings still function properly with the jumper set? Thanks for any input.
