Intel SS4200 - Using Drive-LEDs for Harddisk-Status

Sven Bachmann
I’m using an Intel SS4200 as NAS with Raid 6. After installing a CF-Card with an IDE-Adapter as cheap (and horribly slow) SSD its now possible to put the harddrives to sleep. Since the end of 2009 Linux officially supports the harddisk-LEDs on the front of the SS4200 so why not use them to show the current drive running status? To do so, I wrote a little script which polls hdparm every 10s and sets the LEDs to the drive state (active = blue, suspended = off).
