Day ago I leave my notebook on 30 minutes, and when I came back I was heard
that my HDD was buzzing!
[noisy like the sound of a bee; doing something hard]
I tried to do something, but Fedora don't respond.. even if I press Ctrl+Alt+F2
or Ctrl+Alt+Del..
I wait about 10 minutes..
I was forced to press and hold PowerOff button for 5 seconds for hard-shutdown..
When I turn on my laptop, I found something strange in /var/log/messages file:

I coded the following script. Do not use without checking if the HD temperature
is not going too high. Here is the script that you can activate through
/etc/rc.d/rc.local :
==
#! /bin/bash
#Utility that checks whether the APM level is at 254 if not, reset it there.
SLEEP="120"
while [ true ] ; do
STATE=`hdparm -I /dev/sda | grep "Advan" | sed "s/.*
\([0-9][0-9][0-9]*\).*/\1/"`
ASTATE=`echo ${STATE:0:3}`
if [[ $ASTATE != "254" ]] ; then
hdparm -B 254 /dev/sda
fi
sleep ${SLEEP}s
done
==
It is useful since each time it comes back from suspend or hibernate the value
is set back at 128 so having such a script reset it back to 254 which prevents
the Load_Cycle_Count problem as noted above.
Hope this help.

Nevertheless, it is believed that these APM power settings are the sensible default settings for the vast majority of hard drives and that the current behavior poses a significant risk to the longevity of hard drives used in a wide range of laptop models, so this update should only be blocked if it results in confirmed hardware damage that can be expected to apply to a similar range of configurations.

In fact, aggressive APM is not a bad idea while a system is not on AC, as that system is much more likely to encounter a physical impact. This is due to disk APM settings that let the heads park or disk spin down after an idle period that is shorter than the regular disk access patterns of the OS. Then, the heads are only parked for a very short period of time

Re: [Kernel-packages] [Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime
For me, it's that the OS leaves insane hardware mfr defaults of hdparm -B=128 in place even on AC power. I believe this was fixed in 12.04 but is back for some reason in 14.04 for me... Installing TLP changes to B=254 on AC and retains the B=128 on battery (with the addition of clustering hdd writes to help prevent excessive disk activity and thus load/unload cycles), so provides essentially the same fix with added benefits of actual power saving on battery ethan “A society grows great when its elders plant trees whose shade they know they shall never sit in.” -- an ironic Greek proverb On Sat, Aug 29, 2015 at 6:48 AM, Nick B. nickbr...@gmx.us wrote: What is your test case?

SRU justification: current behavior may lead to premature disk failure in laptops due to excessive unnecessary drive parking. Fix will disable disk cycling by default when on AC power, by correcting an error in the hdparm logic of acpi-support. For jaunty, this issue is addressed in acpi-support 0.115. TEST CASE: 1. With acpi-support 0.109 (hardy) or 0.114 (intrepid) installed and laptop-mode *not* enabled in either /etc/default/laptop-mode or /etc/default/acpi-support, monitor the load cycle count of your hard drive by running 'sudo smartctl -a /dev/sda|grep Load_Cycle_Count' over an interval of several minutes, and observe that it is incrementing. (If it does not increment, your hard drive's manufacturer defaults are sane and you are not affected by this problem.) 2. install acpi-support from hardy-proposed or intrepid-proposed 3. while connected to AC power, monitor 'sudo smartctl -a /dev/sda|grep Load_Cycle_Count' again to confirm that the number is no longer incrementing 4. (assuming that the system is a laptop:) disconnect the system from AC power, and confirm that the number is incrementing again 5. enable laptop mode by setting ENABLE_LAPTOP_MODE=true in /etc/default/laptop-mode and running 'sudo /etc/init.d/laptop-mode restart' 6. reconnect the system to AC power and confirm that the Load_Cycle_Count stops incrementing. 7. suspend and resume the system and confirm that the Load_Cycle_Count is still not incrementing. REGRESSION POTENTIAL: As this patch causes hdparm -B 128 and hdparm -B 254 to be invoked automatically on systems where it was not being run before, there is some risk that this change will have a measurable impact on the disk throughput, power consumption, and temperature of some hard drives. Nevertheless, it is believed that these APM power settings are the sensible default settings for the vast majority of hard drives and that the current behavior poses a significant risk to the longevity of hard drives used in a wide range of laptop models, so this update should only be blocked if it results in confirmed hardware damage that can be expected to apply to a similar range of configurations. Following is a summary of the issue: It is confirmed that some systems are seeing an unusually high number of load/unload cycles on their hard disks, as evidenced by smartctl. It was originally surmised that this was related to laptop-mode being enabled, but this especially affects systems where laptop-mode is disabled. In fact, aggressive APM is not a bad idea while a system is not on AC, as that system is much more likely to encounter a physical impact. This is due to disk APM settings that let the heads park or disk spin down after an idle period that is shorter than the regular disk access patterns of the OS. Then, the heads are only parked for a very short period of time and almost imediately loaded again. Making impact protection much ineffective and wearing out the drive. It can
