I wonder if it isn't more a case of incompatibilit y (bios, etc) than anything else. Reading reviews, it also raises suspicions when the same person seems to get 2 or 3 doa drives in a row. Be that as it may, I have never had a 1+ terabyte drive, but I have had a coupla 1 terabyte WD (green) drive for a few years. Both have performed flawlessly. Hard drive prices need to come back down to earth (flooding in Thailand) before I'll buy any.
