Quit spreading FUD. The cost of building a subverted drive isn=E2=80=99t= worth the time or money for general distribution in the economy. You ne= ed a high percentage of the drive=E2=80=99s physical capacity dedicated = to spare space to get a decent chance of catching useable data in =E2=80= =9Creallocated=E2=80=9D space. Of course your competition can just sell = a higher capacity drive and put you out of business. The easiest way to destroy information is forgetting the encryption key = but most people don=E2=80=99t use FDE.
