Today hard disk maker didn’t build their hard disk like they used to before. Those old hard disk is so reliable that they run for years. But recently the hard disk failure rate is increasing very fast. I have a lot of hard disk at home. In fact I have 10 desktop hard disk and 6 is running right now. 2 of it runs 24/7 in a torrent/media server and another 2 is used for back up purpose.
I have hard disk from Maxtor, Western Digital, Seagate, Samsung. So far the hard disk that always failed me is Western Digital hard disk.
