Heads are bad. If you see disk is not recognized by full model and s/n. That one that you see is information from PCB.

clicking + stopped is not a good sign, most likely head problem.
was it dropped ?

if you have important data on drive, it is highly recommended to send it to a professional DR company.

The HDD was connect to a Asus router RT-N16 and never drop ,router and hdd have uninterruptible power supply .

warranty ends = life ends

I would say you are lucky to survive 3 years with a DM series drive.
the more you power up the drive the worse you will make it.
if data is worth, send it to reputed DR company.
