i too have a 1tb seagate that was lying unused for long until i decided to put it in my now revived pc to work as a backup drive. however found it was having trouble reading data. it already had data on it, of which about 80% or so i was able to retrieve, until one day it finally stopped responding, with some clicking noises. opened it up & couldnt discern anything problematic. it'd spin for a few seconds, head would move, until everything comes to a stop abruptly. will make a video of it & post.
