  <description><![CDATA[Yes, I have seen many tutorials.  Most are followed by comments that they don't work or have certain problems.  Is there an official Ubuntu fix?  If not, could someone please direct me to the best of the many fixes?]]></description>

  <description><![CDATA[My understanding is that this problem only occurs when laptop_mode is enabled.  Fortunately, laptop_mode is not enabled by default on Ubuntu.<br /><br />Only if a user goes out of their way to enable laptop_mode will they encounter a problem.]]></description>

  <description><![CDATA[This was actually documented by the Gnome project years ago when there was discussion about integrating advanced hdd power saving functionality to gnome.<br /><br />The modern drives are very smart and attempting to apply more power saving to them actually mostly just increases the power usage. You really shouldn't have enabled anything extra in the first place.]]></description>

  <description><![CDATA[Yes, it'd be great to have that fixed.<br /><br />There are some settings in /etc/default/acpi-support which seem to be related to this problem. When I tried to use them a few months ago on Gutsy, they didn't seem to affect the shutdown/idle time. Can someone confirm this?]]></description>

  <description><![CDATA[I have quite a bit about that issue in launchpad and it's NOT a trivial issue to fix. Some HDD / Bios ship will inappropriate default and it's not only a Linux problem.<br /><br />However something really need to be done to make sure those HDD won't get broken because of the load cycle... if you can avoid it nobody want dead hard drives.<br /><br />A general HDD monitory tool might be a good idea. Warning the user there's a problem and maybe propose a way to stop the insane head parking that happen on some configuration ]]></description>

  <description><![CDATA[At my laptop, with laptop-mode enabled, I changed the APM settings to 253, and it still would spin-down after 1 minute (which is usual while browsing). I guess the reason of this is that the hardware (HDD) controls spin-down using APM. <br />However, it would be way smarter to predict disk-usage using more info than just disk-reads: while moving the mouse around, and typing stuff, you should never spindown.]]></description>

It's a very worrying issue and does need to be resolved without any further delay, especially in an LTS.<br /><br />Fix this issue and [Ubuntu] Linux might start getting a much bigger slice of the pie.]]></description>

I've read about this issue before and I was originally under the impression it affected desktops too. Reading the comments here I'm hoping that's not the case. While I know how to resort to tutorials and hacks on the internet to fix problems like this, I don't like that I have to.]]></description>

Only apply this fix if you are heavily affected. After applying this fix keep an eye on your Load_Cycle_Count and on your harddrive temperate and make sure it remains below the maximum temperature specification of your harddrive. Everything you do is on your own risk.]]></description>

  <description><![CDATA[Turning off power management of your notebook HD is NO GOD  IDEA as a general advice! Stop telling Linux beginners to do that - they might fry their drives! It is irresponsible to post such advices in the forums!<br /><br />I know what I am talking about since my blog is currently being operated from a notebook - I wasted a HD by following this -B 255 talk, it died within 2 weeks after having turned off HD APM because of a broken ball bearing.... and boy it made some really ugly noises before it died.....<br /><br />There is no simple solution, as the same APM parameter has completely different results on the various HD drives. Also, there are different scenarios, and in some of them you actually want to have agressive APM setting in order to save maximum power. <br /><br />What you guys want is something like a squared circle or getting washed without getting wet. It is not going to happen wihtout a HD database and/or vendor support, as all approaches have to respect different situations and different hardware. <br /><br />The best way currently for some drives seems to be a HD management via good old laptop-mode and low APM values while on AC and more agressive settings while on battery. If you can combine this with a HD drive database, maybe you get what you want. But will not get a "one fits it all" solution.  <br /><br />Read this article here for some more information and a flexible "solution" for some Fujitsu HD drives, if you are new to the issue. And don't switch to Vista because of this issue - Vista seems to have the same problem on many drives.<br /><br />http://vale.homelinux.net/wordpress/?p=199<br /><br /> <br /><br /> ]]></description>

  <description><![CDATA[For me hdparm -B 255 /dev/sda does not even change anything. The drive still spins down and restarts every few minutes when on battery. And the whole thing happens, while ACPI is disabled due to the age of the BIOS. Also WinXP on the same computer does NOT have an issue.<br /><br />This is a big issue directly but even more of an issue indirectly.<br />The first contact with Ubuntu is always by "trying it out". If a cost in hardware wear and tear is attached to that, people won't do that. <br />Also it could lead to Ubuntu-exceptions on warranties, which is not the kind of publicity, that is needed. ( and it could give service personnel an easy way out of fixing your computers, even if such an exception wasn't explicitly stated)]]></description>

  <description><![CDATA[I just finished a "fix" for my laptop with this issue... but now my HD is running hotter than before (46 degrees Celsius compared to 38 degrees Celsius before)... still within the operational temp range... but it's a little unsettling. My load cycle is much better now though... I was at 11 load cycles every 26 minutes before... after the fix I haven't even had one load cycle for multiple hours.<br /><br />This should definitely be a high-priority task for the Ubuntu dev's though.]]></description>

  <description><![CDATA[If it hasn't been fixed, post bug reports, this is the wrong place, because there is no feedback loop anyway. <br /><br />Enabling AHCI (to give you NCQ) could potentially help a bit too, because it allows the heads to move more efficiently, but never actually checked. <br /><br />Talking about it here wont help, because developers have no idea about the specs of your computer, cant ask you to do checks, etc. ]]></description>
