My hard crashed it's not detectable

I had bought 2TB hard disk on Mar 2016 and recently it got crashed when I start system it says disk boot failure I thought WD is the best in market but it crashed though do not use it much.

How am I suppose to get it fixed or replaced ?

Wow. You’ve been waiting a while to get such a weak reply. I have a 1TB WD Blue Caviar that has just disappeared. Won’t do anything. I guess I’ll get a better reply in about two years huh?
