harddisk doesn´t stay in power save mode with xfce4

Dear all,

I´m running Gentoo 32bit with xfce4.4.2 on a netbook and want to have the harddisk in power save mode as long as possible. By using 
echo 180000 > /proc/sys/vm/dirty_writeback_centisecs
the kernel should write cached data every 30min. Then I logged the hd-activity with
echo 1 > /proc/sys/vm/block_dump
and have found the following (dmesg) which comes regularly every 3-5min:

Dec 30 23:17:54 gentoo xfdesktop(26809): dirtied inode 691778 (menu-cache--home-xxx-.config-xfce4-desktop-menu.xml.rc.26809.tmp) on sda9
Dec 30 23:17:54 gentoo xfdesktop(26809): dirtied inode 691778 (menu-cache--home-xxx-.config-xfce4-desktop-menu.xml.rc.26809.tmp) on sda9
Dec 30 23:17:55 gentoo xfce4-menu-plug(26822): dirtied inode 691779 (menu-cache--home-xxx-.config-xfce4-desktop-menu.xml.rc.26822.tmp) on sda9
Dec 30 23:17:55 gentoo xfce4-menu-plug(26822): dirtied inode 691779 (menu-cache--home-xxx-.config-xfce4-desktop-menu.xml.rc.26822.tmp) on sda9

I found the same behavior on three different Gentoo-boxes, one of them 64bit.
What does it mean and much more important how can I prevent this behavior or extent the of doing so time ad libitum?

Thanks in advance

Hrm, you might have to file a bug regarding this.  I'd post the to the ML where Brian (the xfdesktop author) will see the msg.
