How Vulnerable Are Encrypted Hard Drives?

It looks more research is needed before we find out just how safe new disk drives with built-in hardware encryption are.

A group of researchers at Princeton created a stir last week with a paper describing a technique for extracting the hard-drive encryption keys from computers. An email from a reader raised the question of whether the technique would work against self-contained full-disc encrypted drives, such as the Seagate Momentus FDE (PDF) that I wrote about last fall.
