i've been repairing pc's for 20 years, by far the worst drives were maxtor, im not even sure if they still make drives, havent seen one in ages. seagates were somewhat reliable, but will eventually fail, like most things in life. i tend to stick with WD, as i still have WD hdd's that are 15+ years old, and still work. not like i havent seen a bad wd drive before, its just a rarity for me.
