While i was looking up solutions to fix my HDD issues on YouTube, i found something interesting. majority of the videos had Seagate HDD as the one that needed to be fixed, most of em 500,2tb & 3tb capacity, i guess 1 & 4+tb is more reliable for some odd reason. also the same case on forum threads, majority being 2Tb drives . with few exceptions of users complaining about WD, But it was very few. Anyways , i dunno if it's a common case for seagate hard drives to just fail easily or just sheer volume of hdd flooded to the market makes it more used & prone to user damaged so it ends up for repairing for all these videos.
