HDD clicking

The main issue with this clicking is not the noise that I'm bothered, but the fact that hdd sounds like it's really struggling and it could break down.

That description is worrisome in its own right. 

Disk drives do have a finite life. Hands down, they're the most unreliable computer component I use. I recently took a box full of old drives to the county recycling station. All of them had failed in various ways over the years while in service in various PCs, laptops, and servers. I kept the dead drives on hand because they have some interesting bits in them which I've used in other hacker projects but now I'm preparing to downsize and have to empty out my Fibber McGee's closet.

If I were you I'd be making sure I had a complete and tested backup of this drive before it actually does break down.

Interesting to stumble upon this thread as I was debating my old ReadyNAS Duo which is 10 years old now & has faithfully been the sole source of music for my MoOde players all this time, spinning the 2x SCSI drives 24/7 in that time with just a handful of pauses due to power outages.
I've certainly had my moneys worth out of it, but there has never been clicking, just a gentle buzz as it refreshes the library occasionally and when playing music it's silent.
I just hope the next one will be as reliable.
I cant even recall the brand of SCSI disks in it, I know they were identical, I guess I'll find out one day.

I do not wish to further enhance my reputation as a pedant, but are you certain that you are running SCSI drives in your ReadyNAS Duo? What sorcery is this?

AFAIK, ReadyNAS Duo units have only ever supported SATA drives.

I must have used the SCSI drives in another project, my memory is not what it was, looking at my admin screen for the ReadyNAS I used a couple of Seagate ST2000DL003-9VT166's, so sorry for the duff info.
