People on the ubuntuforums are worrying about this problem because quite some people seem to be suffering from it. Just do a search for Load_Cycle_Count on the ubuntuforums. Here are some threads as an example :
Harddrive manufacturers seem to claim most harddrives can handle at least 600.000 Load_Cycles but this is probably an average under ideal circumstances. My harddrive started to die slowly when at a Load_Cycle_Count of 200.000.
IMHO this bug should get critical status because it’s killing people’s harddrives.
The following things might cause aggressive power management :
- your (laptop) harddrive firmware might have aggressive power management defaults (operating system independent)
- your (laptop) BIOS might set your harddrive to use aggressive power management (operating system independent)
- you might have enabled laptop-mode in /etc/default/acpi-support (disabled by default) which will set your harddrive to use aggressive power management
People with laptops who haven’t enabled laptop-mode and think they are suffering from this problem might consider adding the following information to the bug report :
- the output of $sudo smartctl -a /dev/sda
- the age of your disk
- an estimate of the total hours your disk has been running since you started using it (to compare to Power_on_Hours because that value might be off)
- an estimate of the average increase of Load_Cycle_Count during one hour on AC (before applying any “ugly” fixes)
I blogged earlier about this problem :
