I have a Centos installed on a Hitachi 2.5" drive that shuts off really

So every 30 sec, the drive makes the sound of an access activity. I
have looked trying to find what might be being updated. Swap drive
usage is 0 bytes. No activity in /var/log. What might it be and can I
do anything to lessen the drive access (improve battery life)?
I'm sure there are other things as well but first thing comes to mind is
disabling atime for your file systems, to test the change you can do this
(for each of the mount points)
mount <mount point> -o remount,noatime
Oh, I only did this for the mounts in the LVM partition: / and /home
I forgot to do /boot which is a plain old ext3
Still things are quite. This itself is interesting if only ext3 mounts
in LVM partitions not just plain ext3 partitions suffer from this.
OOPS, been 15 min, about, and I just heard the drive seek again. But 15
min I can live with; 30 sec was nerve-racking (on an otherwise silent
system, no fan).
