New md101 - hdd clicks, normal? Is it being treated?

Question

Hard disks

Please tell me, I bought a brand new MD101 macbook pro. During operation, I noticed that he periodically makes sounds similar to the parking of heads on the HDD. I do not observe a special system in the periodicity of sound. I'm new to apple technology, tell me please, is this normal or do I need to urgently test the screw and change it under warranty? The system utility checked the disk, it says that everything is ok.

Answer 1

Modern drives, especially notebook ones, have aggressive spindle speed control settings, and as a rule, after about 30 seconds of inactivity, they turn off the spindle, especially WD. Most likely this is your clicks. But in essence, if the disk utility did not find any errors, then most likely everything is fine.
