Bug Description

my computer is hp540,when i am using ubuntu 9.04,the temperature of my hard disk is usually 52 degree,while in windows xp it is usually 40 degree.
not just me come up with this problem,i have heared a lot people that have the same problem with me.
the temperature is frightenig,and i am afraid it will damage my hard disk.
if ubuntu do not harm my hardware,i will use ubuntu entirely immediately,and get rid of windows xp.

affects: ubuntu → linux (Ubuntu)

Can you post logs (or screenshots) of temp of the HD, and also it is Fahrenheit or Celsius?

   First of all,i will give you a general describtion about my laptop.my laptop is hp540,i am using ubuntu to control my entire laptop,usually the tempera-ture of the hard drive is 46~52 celsius.And when i was using windows xp,it was always less than 40 celsius.
   The fact is,as you know,this is summer,so when i use ubuntu these days,my laptop is really hot,if i use many applications,such as toterm or screen-saver or openoffice,the temperature is very high,as i said 52 calsius.when i do nothing,the temperature will be 45~46 celsius.And in winxp,it is less than 40 celsius,even when i am using many applications.
   The detailed information about my laptop is presented in the "submissio-n.xml",you can open it with firefox.
   In order to give you detailed information about my laptop hd temperetu-re,i managed to record the temperatuer of my wdc every 5 minutes from 090828 23:00 to 090829 12:00,i also took some screenshots.
   I am sorry that i can not give you more detailed information about my hd temperature in windows xp,because i am using ubuntu to control my laptop entirely.Although i can change my laptop into a "windows xp + ubuntu" double os,but i am too lazy to do that.But i can promise you that when i was using windows xp,the hd temperature was always less than 40 celsius.
   Is it just because that i don't know how to configure my hardware?Can you tell me how to cool my hd down?
   By the way,i find that almost all linux operating systems have the same problem.Including debian,ubuntu,arch,puppy.I don't know why.But it is really important to our computers,isn't it?

Appendix:
here are the files i used to monite my system.

ilu,
    would you mind running 'apport-collect -p linux 417570' from the terminal window so that we can gather some environment information on your machine to use as we dig further into this issue?

Thanks!

To confirm whether this is the issue in the above bug you could try running with out AC connected (if this thing has a battery) and see how the temperature manifests. please report back here.

Could we confirm that this is still present in Lucid and Maverick. You can test the live-cd images for this.

I'm experiencing similar behavior on my up-to-date Maverick installation.
I suppose it is because of the aggressive default APM / AAM setting ( =254 ) which does a fine job on the load_cycle_count rising issue but obviously makes the HDD run really hot.
FYI, on Windows 7 I have set APM = 231 and AAM = 128 and the hdd doesn't get hot ( about 41 C comparing to 50 C on Ubuntu with APM = 254 ) and surprisingly there's NO load_cycle_count rising problem. The disk simply doesn't click at all. While on Ubuntu, if I lower the APM and AAM values ( 231 & 128 - just like on Windows ), the hdd gets indeed cooler but there comes the load_cycle_count issue - it raises about 1 point every minute. Now this is quite dangerous.
So, until the described behavior is fixed, I'm staying on Windows. I don't want to brick my HDD.

ilu,
    I really need logs from you before I can move this issue forward.

SolidSlash, do you have a bug open for your issue related to this? If not, please run ubuntu-bug linux from the terminal so that we can get a good bug with logging from you on your issue.

Thanks!
