I bought a machine Acer Aspire v5-131 Intel Celeron 1017U. Everything is working great, found quickly how to fix not working brightness regulation. But was unable to solve hard disk clicking problem (occurs every 1-3 sec). I have only one partition (/), no swap.

I tried doing the following solutions found on the net:

sudo hdparm -B 254 /dev/sda or sudo hdparm -B 255 /dev/sda

Neither did stop the clicking. And: gedit /etc/hdparm.conf:

 /dev/sda {
    apm = 254 #(or 255)
    apm_battery = 254 "(or 255)

The problem does not occur on Windows 7/8 at all (although I removed them completely). Ubuntu stops the clicking after I connect the power cord.

Thanks in advance, if anyone knows the solution.

Tried standard 64 bit version 13.04 and XFCE, the results were the same.

Note: When dealing with possible physical hardware issues with hard drive, make sure that you have a current backup just to be on the safe side. You may want to take a look at Clonezilla.

Clicking noises from a HDD are usually the beginning of a drive failure. The clicking is the internal mechanism attempting to access the drive and being physically unable to properly mechanically engage the position for reading.

Now a little on the bright side, I have had this happen before with a Seagate drive. It has to to with power management on the drive. I updated the firmware, and that fixed it. See if the drive manufacturer has a firmware update on their website.

In case the firmware update doen't fix it, make sure that you backup the drive just in case.

I have the V5-131 too. This clicking isn't the hard disk, its caused by the power saving option of the sounddriver:
