It seems that there are some at Ubuntu who feel it is more important
to make the bug statistics look good than it

But note also that with how often Ubuntu touches the disk, it will quite
simply never park the heads, even if it is inactive. Actually, the
aggressive APM isn't really the issue (although it will, obviously,
affect the live to some extent), it's more that Ubuntu touches the HD on
a regular basis,
I didn't see atime mentioned on the wiki page. Logging in fails for me
right now (takes forever), so perhaps somebody else could add this info:
If you're looking for something that definitely does cause disk activity
every 30 seconds, it's atime updates. When enabled (which they are by

I'm 99% sure that the problem lies not (so much) in the aggressive APM,
but in the combination of the aggressive APM and some spurious constant
disk activity. If the disk activity weren't there, it wouldn't be so
much of an issue, and if the APM weren't so aggressive, it wouldn't be
so much of an

You should backup all your data!
It's not sure to crash but you should know that number is over the
maximum taken from Hitachi specification about Load/Unload. It says that
300k cycles are bonded but they tested over 1000k loads (not cycles).

Hi,
Please, can you post kernel versions and hdparm parameters used in
init-scripts?
Detailed information about hdparm calls during start-up and while
changing power source in OpenSUSE and Fedora could be very interesting.

As you can see that hdparm executions are related to laptop_mode, not
directly to start-up. If Ubuntu can't identify your AC status is another
bug, not related to "power.sh".

Init system calls hdparm script but my "hdparm.conf" had no-section.
I've added one for adding "-B254".
Using "rgrep -i *" in "/etc" can tell you a lot of things but if you
want more, for example, change hdparm binary with a wrapper script that
calls real hdparm and logs its execution (date >> /va
Hi,
In your case (24x7), you should use a value for "-B" that can increase
the life of your hard drive having a reasonable temperature. My hard
drives tells (through smartctl) 41ºC and 13/51 for actual and min/max
temperatures. I'm using "hdparm -B254" since yesterday because it
reached 400k loads
749 times is not a lot of start/stop count but 600k is huge for parking.

Pedro

But it's said that a hard drive only supports around 600k Load cycles.
I saw that Ubuntu puts "-B255" to disable APM but it stills do around
3-5 unloads/loads in a minute. With "-B254" it doesn't unload...

It was not meant as a fix for the problem (I have noatime since a long

Hi,
Worse, a few (or most) laptops have the default behavior of park heads
about 3 or 4 times in a minute. This is fixed in my laptop with "hdparm"
but using "-B254" instead of "-B255".
I added a line in "hdparm.conf" for my disk with "apm = 254". Also
changed "power.sh" to set "-B254" instead of
In that case, something should be done, as aggressive power management is
enabled by default - and as the reports demonstrate, this is causing a
significantly shorter disk life than on other OSes.

I wonder if it's going into sleep, and then trying to write to the log
that it has gone to sleep.. That would be a big 'duh'.

Thanks for confirming. So now we'll have to determine sane default values.
I did some very unscientific tests using the command
smartctl -d ata -a /dev/sda | grep 193; hdparm -B 180 /dev/sda; sleep 600; \
smartctl -d ata -a /dev/sda | grep 193; hdparm -B 2
