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 think I found solution to stop increasing Load_Cycle_Count.

The solution:

/dev/sda:
setting Advanced Power Management level to disabled
]# hdparm -I /dev/sda|grep Advan

Now Load_Cycle_Count stopped increasing!

Bug confirmed un a Toshiba Satellite A210-FS3
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.

Re: [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?

Please do not use it as such (even though it has been used as such already). You can scan through the bug for links to the Ubuntu forums where many, many different questions have been asked, answered, and re- answered. The temporary workaround is just below. See https://wiki.ubuntu.com/PowerManagement for an overview about what is involved and for a remedy. 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.

[Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime
I gave to my wife a new Samsung N150 Plus Netbook last year. Last month the hard drive died but the warranty covered a new hard drive, so it was fine. Now with the new hard drive i was able to hear every 6 seconds that the heads are parking, and i tried many things and i cannot make it stop. Now i wonder the first hard drive (the one that died 1 months ago and my wife lost tons of data) died because of this bug. I know that this is an old bug now, but in this netbook is defenitly back and i tried adding this command in /etc/init.d sudo hdparm -B 255 /dev/sda even i tried to edit the laptop_mode.conf settings to do no power management in this hard drive and i had no luck, the packages had changed over the last versions of ubuntu and i do not know where to edit to disable this powr management. Now this hard drive has over 16000 load cycle counts and it keeps growing. Anyone has starting to experience this? how do i stop this power management in order to save this drive because the netbook warranty just expired this month? regards -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/59695 Title: High frequency of load/unload cycles on some hard disks may shorten lifetime To manage notifications about this bug go to: https://bugs.launchpad.net/acpi-support/+bug/59695/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@JoonasSaarinen It is normal only if done not too frequently. Because otherwise, it can kill a drive. And that is not just theoretical, it can happen much more quickly than you may think: I had a drive with that issue, but very quiet so I did not notice.

It looks like WD BEVT-series was not mentioned here and the kernel.org is still down. I just noticed huge Load_Cycle_Count on the WD1600BEVT-80A23T0. It almost reached 300 000 when I stopped it (299 252 to be precise) with hdparm -B 255 /dev/sda -B 254 didn't help, it just _ignored_ it. Power_On_Hours is 2771 and that gives an average of 107 cycles per hour. Which is still very small compared to what I've heard today: it parks every 3-6 seconds (!) on the battery.

I think the workaround for the problem is to install laptop-mode-tools and in /etc/laptop-mode/laptop-mode.conf change line: BATT_HD_POWERMGMT=1 to BATT_HD_POWERMGMT=254 This of course sets default disk APM to 254, but with laptop mode tools my WD Scorpio Blue 500GB stays pretty cool (about 43 degrees Celsius) and there is no idle drive clicking from now on.

Unfortunately, the dirty fix of setting APM to 254 doesn't end this issue. My hard disk is WDC WD2500BEVT-75ZCT2 (Dell Studio 1555) and, on Ubuntu 11.04, it gets really hot on the default settings. (up to 50 C on idle and even 54 C when copy/pasting) The load_cycle_count doesn't seem to go up very fast though. Setting to, for example, 239 makes the temperature go lower but then the load_cycle_count increases like crazy. I mentioned the 239 value because I use it on Windows 7 by applying it by quietHDD and both the temperature and load_cycle_count problems are non-existent.

** Description changed: - This is not a support forum. Please do not use it as such (even though - it has been used as such already). + The kernel wiki gathers info about drives with too aggressive power saving defaults. A script called storage-fixup is also available. + https://ata.wiki.kernel.org/index.php/Known_issues#Drives_which_perform_frequent_head_unloads_under_Linux + + + This is not a support forum. Please do not use it as such (even though it has been used as such already). You can scan through the bug for links to the Ubuntu forums where many, many different questions have been asked, answered, and re-answered. The temporary workaround is just below. See https://wiki.ubuntu.com/PowerManagement for an overview about what is involved and for a remedy. 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 happen when the disk asumes aggressive APM settings (like many laptop disks) and the OS does not take care to set the APM settings accordingly to its current disk access pattern. This problem has been confirmed in Ubuntu as well as in other distributions and on MacOS X and Windows. Symptoms of this bug are: * Frequent HD clicks -- more than one per 3 minutes while idle, louder than the typical access sounds. Often more than twice per minute. On some disks, the click is very quiet * Rapidly Increasing Load_Cycle_Count as displayed in the final number in sudo smartctl -a /dev/hda | grep Load_Cycle_Count (where /dev/hda is replaced with your own hard disk device) The problem is only present due to the existence of *all four* of the following factors: * Hardware is set (default or otherwise) to aggressive power management, causing heads to park. (default behaviour of many drives and often the only user available type of power management) * Disk is touched often, causing heads to unpark. (default behaviour of many distributions) * Drives are spec'd to a limited number of these

This bug is far from being fixed. I am using the latest -proposed packages in intrepid. Same behavior for me as for other reporters: When I boot up on AC power - no problems. When I go to battery, the issue appears and will STAY even when I reconnect AC power. I get around 10 load/unload cycles per MINUTE. It will only go away after a reboot. This happens regardless LAPTOP_MODE=enabled or =disabled. I am using a Thinkpad X200s with a Seagate ST9160827AS hard drive. Please remove the fix released tags - this issue is NOT fixed. Plus, if I may add, I find it silly to claim that this cannot be fixed entirely because the hardware sucks.

(I started with 7.04 and then upgraded the system up to 8.04.) Then today, I decided to install 8.04 from scratch and the bug is not there anymore (of course, I haven't reapplied the ugly fix, so the packages now seem to work fine).

On battery the load cycle does increase, because it is useful to allow disk power management: for power saving, and to protect against falling. It's been calculated that even for pretty extremely mobile usage, your disk should be fine for a very long time. On AC your load cycle should not increase (much).

[Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime
Reducing the frequency of unparking is nearly impossible in Ubuntu, at least for the developers atm. It isn't enough to higher the DIRTY_RATIO like laptop-mode does or exit or disabling hal-polling. If apps like Firefox are used they poll very often. I personally got longer sleep times (nearly a minute) after doing the mentioned and moving /tmp and the firefox profile, macromedia and java directory to tmpfs. The problem is that the directories have to be synced to disk before shutdown and there are several more apps that poll recently I guess. I still think it is the best to poll affected hard drives (high SMART parking values) recently and don't change the apm value. Of course this only makes sense if the hard drives doesn't get as hot with polling as with disabled apm. At least for laptops the problem might be gone soon when SSDs are used more recently so just waiting might solve the issue too ;) . -- High frequency of load/unload cycles on some hard disks may shorten lifetime https://bugs.launchpad.net/bugs/59695 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime
Wouldn't it be the task of DeviceKit-disks to check for the drive's health and disable parking when it's happening too often or when the disk is near its end of life? I know it already does some SMART checks, so it could be easy to add this feature, and IMHO it's the place where things like that should be done. ** Changed in: acpi-support (Baltix) Status: New = Fix Released -- High frequency of load/unload cycles on some hard disks may shorten lifetime https://bugs.launchpad.net/bugs/59695 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Maybe it is/was better to poll the hard drive on effected systen every x seconds to prevent spinning down but still let use the ohter features of apm.

Not solved for me either. Noticed by loud clicks. Laptop mode disabled. Seems to only appear once I suspend the computer and bring it back from suspend.

Would it be possible for some influential ubuntu developer to talk to manufacturer and ask what policy would they use on their drives?

Re: [Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime
Hi, This problem really exist on Ubuntu 8.10 and it's even worse than earlier because some packages was updated to fix this problem, some system files works different than earlier to fix this problem and effect of this fixes is that people simly couldn't solve clicking their hard drives because scripts, ugly fixes and all simple methods not working with updated files of Ubuntu 8.10. People from Ubuntu could say: So why people still edit those files if it's no effect with this problem. Because most of people tried to make it so easy as You discribed in: https://wiki.ubuntu.com/PowerManagement And still hear hard disk clicking. What schould They do? Install Windows to stop it or what? Instruction from PowerManagement link is: ENABLE_LAPTOP_MODE=true in /etc/default/acpi-support and it's simply not working. This problem exists so long. There was so many ugly and simle fixes that could stop clicking but now non of them works because Canonical updates files to solve this problem and updates could not solve this problem and updates disabled almost every simle mathods to stop problem manually. Many new people hear recomendation of Ubuntu from other users. Finally install this system and one of first subject on every Ubuntu forums is How to stop Ubuntu to kill your hard drive. For me is very bad recomendation. Could someone give me a link to original and clear: /etc/laptop-mode/laptop-mode.conf Because aftes so many solutions I'm not sure about what is clear Ubuntu 8.10 configuration in this file.

[Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime
Steve Langasek: sure, there's a tradeoff... but with sufficient knowledge, perhaps we could make it less bad. Suppose the hard-drive is specced to 60 load-cycles. With smartctl we can measure the current number of load-cycles. Suppose there have already been 70 load- cycles: wouldn't you think it'd be pushing your luck to park the head frequently, even if it saves power in the short run? More seriously, suppose you decrease or stop that behavior earlier, say at 50 or 30 load-cycles: so an older drive will use more power on battery, but at least Linux would then obey the principle of do no harm. (If the hard-drive dies, the user has to replace it; if the hard-drive is just inefficient, the user still has the choice of replacing it, and is also less likely to lose data.) Now we can look at something desired like There should be fewer than ~15 load cycles per hour, except during heavy usage while on battery. that makes new drives last at least four years... if we adjust that number 15 in proportion to the actual (spec - load_cycle_count), then we'll manage to keep the drive pretty much safe from this kind of wearing-out! however! - we may not know the spec (is it bad to assume that it's 60)? - hard drives seem to be quite uncooperative: there might not be *any* good way to tell one don't park any more often than X times an hour, even though there's a darned simple algorithm (disk remembers the last time it parked the head, and refuses to park the head again for the next 1/X hours). But maybe there's a way we can ensure that (frequent hdparm -B to different values? Is doing that likely to wear out the drive in any odd way?) -- High frequency of load/unload cycles on some hard disks may shorten lifetime https://bugs.launchpad.net/bugs/59695 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Parking is handled by the drive itself according to the APM power management settings; we don't really have a good interface to control parking more finely than that. The only other approach to reducing the number of load cycles would be to reduce the frequency with which Ubuntu requires *un*parking the drive; that's worth investigating, but is going to take a while to get to the bottom of and is probably not something we would change in existing releases via SRU unless the fixes were obvious and straightforward. -- Steve Langasek Give me a lever long enough and a Free OS Debian Developer to set it on, and I can move the world.

enubuntu, It is intented that the hard drive be parked when running on battery, there's a trade-off between hard drive longevity and power usage.

Steve Langasek, ok the hard drive can be parked when running on battery, but sometimes it is too much (particularly when you do nothing, you let the computer alone on battery). Last time, it parked about 400~500 times in 1 hour. That's why I reapplied the fix which always set hdparm to 254. -- High frequency of load/unload cycles on some hard disks may shorten lifetime https://bugs.launchpad.net/bugs/59695 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
