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. -- * Greg Smith gsmith@gregsmith.com http://www.gregsmith.com Baltimore, MD
