so i know that a constant clicking noise means the hdd is bad but this only does it when writing data. like massive amounts of data... i just got done building my gaming pc and used my old 2tb hdd which although it had a fall recently seems to be working fine. After about 20 minutes in to downloading most of my games (around 300gb) it started clicking 3 clickes then like a 10 second pause. it is pluged into a 6gbs sata port if that matters. So is the hdd going or was it just writing too fast?? at the time of this post im creating backups of it and it doesnt seem to be making the noise while reading.
