guy i have an infamous 1TB seagate that recently decided just give up on me.
It was flashed to SD1A from SD15 and works fine for some period of time, but suddenly it just not detactable anymore and making the clicking noise once power is connected (I am using it as external with HDD dock).

Does this mean that my HDD is totally dead?

I did tried to plug into my PC directly with PSU and the same results appears.
