I've read that much of the damage that causes hard drive infant mortality 
is related to shipping.  The drive is fine when it leaves the factory, 
gets shaken up and otherwise brutalized by environmental changes in 
transit (it's a long trip from Singapore to here), and therefore is a bit 
whacked by the time it is installed.  A quick post-installation burn-in 
helps ferret out when this happens.
