Little trick to make hdd work even more quiet!

You can make HDD inside MyBook Live drive work even more quiet by changing AAM value.

It is perfectly safe to do that. You will loose maybe just 1% of drives speed performance by doing that.

To change value use following command from root account:

hdparm -M128 /dev/sda

 After that you can execute:

hdparm -I /dev/sda

and it will shows tons of info about your drive.

You should see following text somwhere - Recommended acoustic management value: 128, current value: 128

That means you set it correctly.
