Seagate, Hitachi working on disk encryption

Seagate currently sells an encrypted hard drive for laptops, but now they and Hitachi are each working on encrypted enterprise drives as well.

There are also issues related to drive interface compatibility. Overly complex or not, it's hard to argue against more security.
