Yes, but it`ll cost ya. There are disk drives that secure the data by
encrypting on-the-fly all the time, and decrypt on-the-fly so it all
happens transparently. They`re `enterprise` models, sometimes
with odd (SAS, fibre channel, whatever-it-is-this-decade) connection
requirements.
Those drives store an internal key that can be overwritten when you want
to lose the data. Even `bad blocks` are encrypted, so the loss of the
key makes every bit of the data on the drive into... semi-random bits.
