CrystalDiskInfo is also useful (go for standard edition - portable). In particular look at reallocated sector counts. I've got a number of Seagates getting quite old now and reallocated sector counts is zero for all of them (touch wood). They are all 1TB.
I buy WDs now but they could also fail at any moment. I still buy only 1 or 2TB HDDs - spreads the risk.
