hdparm power save, 15 seconds of spin, 5 seconds of rest...
 
I tried using hdparm to save some power and heat on my laptop hard drive. Currently I am using this command:
$ /sbin/hdparm -B 1 -S 12 /dev/sda
It will finally spin down after awhile, but then it just spins back up, especially if I access a web page. The disk access light turns on, I just don't know why it is accessing the disk.

It is writing to the drive from the browsers cache settings my guess. Maybe set it to 0 cache will help. I don;t know for sure on that. Possible other things going on from cron jobs and even writing to the log files.
