How common if at all is it to get 2 hard drives and both are defective certified from the manufacturer . I saw what I thought was a great deal on a 500 gb Seagate HDD . when the first one didn't work I said OK stuff happens when the second one failed I got in touch with Seagate they had me go through a few diagnostics . when I told them the drive was not even making any noise just dimming my system and preventing a boot up the verdict was in . my problem is I already have a Seagate 250 gb chugging away , I would like to stay with the brand but my loyalty only goes so far . I heard WD has pretty good Hard drives
