Can't you take an ATA drive off line for 10 years and plug it back in
when you need the data? Does the drive need to constantly re align
the magnetic dipoles on the disk?
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.
