However, keep in mind that due to another bug added to this one, even desktop computers with desktop drives can end with this kind of settings, AND the 20 seconds idle set by ubuntu's scripts is WAY too small

It is a Ubuntu issue, not the entire Linux fraternity. This thread has always been a Ubuntu issue (pfft title.!). So people on Ubuntu should question/ask/care more probably. Like I said before, you are making a mountain of a mole (I agree a somewhat placid idea), it is fixed in many distros, and subsequent updates in Ubuntu will fix it too or might have already, I'm not sure. Don't be paranoid, please! And don't FUD, you will make others scared. Probably dig more on it at Ubuntu forums.

For those who can't come to gripes with the situation and are getting paranoid (justifiably), I strongly recommend dropping (Ubuntu)Linux now, lest you come later and then shout all over the forums about it. Prevention is better than cure, so better do it now.

*The reason why I might consider it a non-issue or a lesser grave issue is that the entire topic about it has went down subsequent threads in Ubuntu forums, meaning it is not that hot a topic it is made out to be here, which in itself says the issue is almost sorted. Of course, these are my opinions. YOMV.

Also I would like to add that it would help in your confidence if you can visit the #Ubuntu support channel on IRC, where you will get a direct reply, once and for all, letting you know on the issues.

You should find out whether your hard drive is under risk.

hmm..so if windows doesnt install on my PC..is this a good situation to try
Fedora 10

or Mandriva 2009 Spring One (distro hopping excuse

)

Fedora 10 or Mandriva dont have these issues right ? for laptops ??

Opensuse had it. *bugzilla.novell.com/show_bug.cgi?id=386555
But now it is marked as solved. so I am waiting for the release of opensuse 11.1 to try.
Dont know if the bug is in fedora/mandriva. in any case, its better to check load cycles using smartmontools after installing the distros.
*smartmontools.sourceforge.net/
Please post your observations after installing fedora/mandriva. I also need a distro for my laptop. I am too afraid to try the hdparm fix

. People have noticed the temperature of their harddrives rising after using that fix. Cant wait for dec18. opensuse 11.1 will release that day.

does this affect desktop harddirves too as you specifically mentioned the word laptop.

Power_On_Hours = 331
Load_Cycle_Count = 17780
So that makes it 53.71 Cycles / hr. You can now calculate how long your hard disk will last by taking into consideration the number of hours you use it daily.

Also, check that airflow temperature. its 59 in your case.

A quote from this page: *ata.wiki.kernel.org/index.php/Known_issues#Drives_which_perform_frequent_head_unloads_under_Linux

"Note that modern laptop drives are supposed to unload frequently to save power. Unless the unloading is excessive, disabling powersaving is not a good idea. It seems that most modern drives are rated for 600,000 load/unload cycles which translates to about two years of uptime at 35 unloads per hour. Even when assuming continuous 12 hours of usage everyday, this means the drive will only reach its rated load/unload cycle limit after four years and shouldn't be considered malfunctioning. Please only report cases where the expected uptime is significantly lower than two years."

Here is the explanation of the S.M.A.R.T Parameters

What is the status of the temperature and load cycle counts now that u have XP ?
smartmontools is also available for XP. *sourceforge.net/project/showfiles.php?group_id=64297
Check your load cycle count in the difference of one hour and see what count you get for one hour doing normal work with XP installed.

Re: VERY IMPORTANT INFO: Hard Disks being Killed in Linux

I have a laptop with Ubuntu (second last version)

Am I at risk?
Is having multiple OSs risky?
Is using Live CD increases the chance of infection (damage)?
Is there some kind of protection against this risk?
Are new sub distros equally dangerous?
Will it become an epidemic?

Re: VERY IMPORTANT INFO: Hard Disks being Killed in Linux

@amit..read thread carefully from the start ..u will know ..

@Jh ..i will check from home once I reach (Office sucks

will reach by 9pm or 9:30)

Offtopic : one prob in XP...I have installed winXP sp2..

my 5.1 speakers arent giving that good sound as wid ubuntu VLC player???
seems they are playing only 2.1 wid winamp , WMP, VLC etc in XP ?
How to reslove that ? I have updated MB drivers (915 M drivers) from intel site..still no diff

Re: VERY IMPORTANT INFO: Hard Disks being Killed in Linux

How do I check my HDD life on my ArchLinux installed in a Seagate 80GB SATA HDD on my desktop ? Its showing poor performance on my computer and several DVDs and CDs got junked half way through writing process due to some access error I guess. Brand new non scratched discs.

Edit: This means anything ?

Re: VERY IMPORTANT INFO: Hard Disks being Killed in Linux

MetalheadGautham
Whats the output of
smartctl -a /dev/sda | grep Load_Cycle_Count
on your system?

Anyways this HDD killer bug affects only laptops and that too when they are running on powersaving mode.
Do
man hdparm
and see if there is something you can do to boost performance of your harddisk.

PS: Hitboxx, please stikify this thread. Looks serious and important.

Looks Ok from that SMART data. BTW, the load cycle bug IS NOT present on Desktops.

Whats the output of
smartctl -a /dev/sda | grep Load_Cycle_Count
on your system?

Anyways this HDD killer bug affects only laptops and that too when they are running on powersaving mode.
Do
man hdparm
and see if there is something you can do to boost performance of your harddisk.

The output of smartctl -a /dev/sda | grep Load_Cycle_Count on his system would be null as that parameter is not available for Desktop hard disks.

Power_On_Hours=779

So, my cycles per hour = 6330/779=8.1.
I am safe.

What is the status of the temperature and load cycle counts now that u have XP ?
smartmontools is also available for XP. *sourceforge.net/project/showfiles.php?group_id=64297
Check your load cycle count in the difference of one hour and see what count you get for one hour doing normal work with XP installed.

I am anxious to know the results of this.

59232/1459 = 40.597669637

Hmm, now how do I interpret this..?

esumitkumar · Dec 9, 2008

I installed smarttools in Win XP ..Its showing
Airflow Temp = Past 50
Power On Hours = 344
Load_Cycle Count = 18129

So it comes to 18129/344 = 52.7 ????

So less diff than Ubuntu ??

What does it mean ? Suppose I run my lappu for 12 hours a day

so 52.7 *12 = 632.4

and a HDD survives 600,000 so 600,000/632.4 = 948.76 days ?

that means roughly 2.6 years ?? Is this calculation correct ??
