Comment 12 for bug 1022511

Yes I aggree that the driver level is the place. I was considering having a clear() method that could be specialised if required.

The faster method currently is specifying a small size that would clear out partition tables/encryption keys.
Also people may specify "none" and have separate async scrubber as described in comment #4 for example

As for having the clear method specified with the delete command,
i.e. overriding the default clear method, that is further functionality
I think which is less pressing (if needed at all), and could be pused to Grizzly I think.
