Delayed Spin up

[Circlenaut]

I'm trying to get this to work with my 180 watt file server. I currently have 4 seagate 1TB in there. If I leave only 3 drives the system boots fine but if I activate the 4th drive the computer shuts off a few seconds into boot. After the 2nd boot it starts up just fine (the computer reboots automatically). I have a rocketraid 3510 and tried to set up staggared spin up but it doesn't seem to work. No matter what setting I leave it at all the drives start up at once. Am I doing something wrong?
