Hello,
I'm long experiencing an annoying clicking noise coming from my hdd,
looking for info on the subject I
found the Known issues page at:
https://ata.wiki.kernel.org/index.php/Known_issues among others.
I've tried many possible solutions involving the use of hdparm (apm,
spindown_time, etc) to no avail.
I'm contacting you because my problem is very strange it seems to occur
randomly, it in fact occurs when I leave the laptop idling and when I'm
using it but at times it disappears completely. I've checked it taking
note of the Load_Cycle_Count parameter.
I've attached the output of the following commands:
dmidecode,
hdparm -I /dev/sda and
smartctl -a /dev/sda
Hope it can help.
Thank you.
