Hard drive failure is a common thing is these modern years due to: outsourcing, high density storage, and many other reasons. Some people make a big deal out of the failures… sure it can be expensive if you must recover you data but its not the end of the world. The biggest issue is that the fan boys of certain brands will attack another brand when it has failures typically evolving into a fight between brands.
Take for example the newer Seagate Barracuda 7200.11 drive failure… Some people are using that as a excuse to bash them and promote other brands. Tho there is a forum thread started on a forum that is collecting info on working/dead drives from that series…. I feel that is a better way to handle it.
Basically expect more drive failures in the years to come due to larger and larger drives.
