Sony releases lockable hard drive Sony releases a $300 portable 80 Gigabyte USB 2 hard drive that will lock itself when you're away, as determined by the wireless keychain dongle. Alternatively, you can use a password other than your child's/wife's/highschool sweatheart's/college roomate's name and pocket the $300 to blow it later on something else you don't need.   ¶ 12:39 PM
