Sorry, Stephane I didn't want to bother you. I wanted to make
clear that I have tried to read before asking questions.
Thank you for your useful information.
BTW: I have installed a similar program 'noflusd', too.
This is also available as *.deb at
>From 'man noflushd'
noflushd monitors disk activity and spins down disks that
have been idle for more than <timeout> seconds.
noflushd actually used to live in some versions of
bdflush, but since kernel version 2.2.11, bdflush has been
completely replaced by the kernel-level kupdate daemon.
When noflushd decides to spin down an idle disk, it syncs
the filesystems, calls the external skript /sbin/noflushd-
spindown that handles the actual spindown and stops kup-
date, so all writes to block devices are suspended. Spinup
happens on the first read request to the disk. noflushd
then calls the external skript /sbin/noflushd-spinup that
handles spinup if necessary and restarts kupdate.
Sending signal 10 (SIGUSR1) to noflushd forces the daemon
to spin down disks immediately.
IMPORTANT: noflushd is mainly intended for use on note-
books and currently can sensibly handle only one hard
disk. Per default, it monitors /dev/hda.
