Current hard drives have a warranty of up to 5 years. I take this as a
signal from the manufacturer that the failure rate rises significantly
after that time. Check out the bathtub curve on Wikipedia:
In fact, the manufacturers are probably using planned obsolescence.
I've heard that the bearings in the motor are the main problem; they
eventually cause the tracks to show up in the wrong place under the head.
However, I've also read that a hard drive kept offline most of the time,
as long as you don't approach 50,000 power cycles, has double the
lifetime of a drive used for typical desktop operation. Sorry, I don't
have any sources.
