Re: How do I prevent hard drive from clicking?
Yep, laptops use to park often the disk heads to save battery and prevent the effects or rude movements. But discs are designed for a life of 600000 parks. Less than 15 parks / hour should be fine.
To see what is the state of your disk, please install smartmoontools from the repos.
→ gives you all the info.
smartctl -a /dev/sda
Look at Power-on-hours (hours the disck has been running, and Load-cycle-count (times the head has been parked). THe ratio should be <15 aprox (incremental).
→ disables the head parking. In some systems it's 255. In this state the disk is exposed to the effects of shaking the laptop, so be specially careful. Also the disk will heat up more. You should check out its temperature often at the beginning ("smartctl -a" will tell you).
hdparm -B 254 /dev/sda
All the above is NOT persistent. To make it persistent you should make a .sh script and save it to some places at /etc/acpi/. You can find more details here
Hope this helps
