[Ubuntu] High frequency of load/unload cycles after suspend to RAM
There is a known problem in Ubuntu connected with high frequency of load/unload cycles on hard disk.
Here are useful links:
I used approach from Ubuntu forums and Load_Cycle_Count stopped increasing. Unfortunately, everytime when I woke up my Asus F3F from suspend to RAM (even it was on AC power), Load_Cycle_Count started dramatically increasing.
Here is a solution:
#!/bin/bash if on_ac_power; then hdparm -B 255 /dev/sda else hdparm -B 128 /dev/sda fi
I saved this code as /usr/lib/pm-utils/sleep.d/99-fixhdd.sh and made it executalbe:
chmod +x /usr/lib/pm-utils/sleep.d/99-fixhdd.sh
Since this fix, everything is OK.
