Ok who likes what power supplies and why?  I have 15 seagate baracuda hds ranging from 500 to 1tb. they will all be 1 tb drives soon. i also use an asus m2n32-sli delux mb and an amd athalon daul core pross. i curently have a PowerUp GEN-6803 800-Watt Power Supply - SLI-Ready, Dual 80mm Fan power supply and i hate it. a few of the 4pin molex conecters cause my unraid server to shut down as soon as i start it up. i have to unplug them wait till its started up and then plug them in in order to use them.

Might be too much power draw on the 12V rail for the spike.

 

Have you tried setting power up in standby on your drives?

 

This will sort of stagger spin up the drives.

 

Here's my script, you will need to define your devices on the line below.

Also, it may take longer to come up as each drive is spun up as it is accessed.

 

I know this works with my 1TB wd green drives.

It "should" work with later seagate drives.

I suggest testing it on a few drives to begin with.

 

 

 

root@Atlas /boot/custom/etc/rc.d>more S01-hdparm

#!/bin/bash

 

for disk in  /dev/sdc /dev/sdd /dev/sde /dev/sdf /dev/sdg

do

        # S120

        hdparm -S242 -s1 --yes-i-know-what-i-am-doing ${disk}

        hdparm -I ${disk} | egrep -i standby

done

 

You might want to consider a 12V single rail power supply like from PC & Cooling, Seasonic or Corsair. I use a Corsair CMPSU-650TX which has 52a on the 12V rail; great supply.
