Can't contact PlayStation so I'm asking here. (more below)

My ps4 pro recently started making clicking sounds after power off or after standby. 

First I thought maybe the power supply but the sound coming from the hdd side. But it could be some relay. Because the psu is quite long inside. 

Anyone else had similar issue? 

I dont want to buy a new hdd if not needed. 

Thanks in advance.
