Well, my 500GB Western Digital survived and work well for the last 3 years now, so I cannot assert my sentiment towards latest products. Still, hardware failure is to be expected to certain degree because the nature of mass produced stuff. Among many other things that could cause it as well.
iirc, drives are tend to have at least a year replacement warranty. Components has up to 3 years warranty coverage by average. Might want to look up for that too. Who knows, it might still covered by warranty.
Which reminds me that I forgot to ask, what brand is this problematic drive of yours?
