In my opinion, Hard drives ought to be scrapped altogether, no matter how new they are between 1 year and 3 years later they die. Too much can go wrong with fast-moving mechanical parts, just like in a hard drive. Whats wrong with using Solid state memory? We already have 2GB Compact Flash cards, it wont really be that long before they get up to 6, 10GB, it makes sence to me.
