HDD sleeps randomly

[organicchemistry_01]

I have a seagate 14TB disk that randomly sleeps, I have read from several sources that this damages the disk easier. How do I just configure my system to make the hdd sleep say after 20mins of inactivity?

You could take a look at hdparm with the "-S" option.
Be careful, hdparm is a very powerful tool which may
damage your system if used incorrectly.
