idle HD spin down standby/sleep, laptop mode?? (seagate 7200.7)

[Kevin Bowen]

Are noflushd and laptop-mode meant to be used together? I was under the
impression that noflushd was obsolete (it doesn't seem to be packaged for
modern distro's anymore). Also, it seems like it is just doing the same
thing as hdparm -S, isn't it? In any case, I tried it out, and it doesn't
seem to want to work with my primary drive (the SATA), it says "No stats for
hde. Ignorning." 

The other stuff (hdparm and laptop-mode.sh) is what I had already done and
had not worked.

Also setting this up recently I found this message very helpful:

a non-encoded version of the laptop.sh script is at

add your hdparm commands to /etc/rc.local and that should do it.

enjoy
