Debian hdd spindown
From NAS-Central Buffalo - The Linkstation Wiki
If you're not using your Kurobox 24 hours a day, it could be good to allow the hard drive to spin down and reduce noise and power usage. For this you'll need to install hdparm to tune the sleep delay, and configure syslog to prevent it from writing to the disk, causing it to wake up every 20 minutes!
