Self-Encrypting Hard Drives and the New Security 205

In a recent blog post, CNet's Jon Oitsik has called for a policy shift with respect to data encryption. A new standard by the Trusted Computing Group promises the availability of self-encrypting hard drives soon, leading some to call for immediate adoption. Will this create even more security problems due to lazy custodians, or should someone responsible for keeping your information safe be required to move to the new hardware? Hopefully the new hardware comes with a warning to continue to use other data protection measures as well.

Sorry, you are all wrong...
a) you have disks silent errors (because error-correcting codes corrected them) that will copy sector data to a reserve sector without notice, that makes your old data inaccessible at software level but readable at controler level
b) you can use high resolution magnetic imagery to recover several rewrites of the same track
c) in my books, a hum is very far from random, it's predictable !!!

Physical destruction is the only reasonably secure solution.
