Sorry to hear that, mate.
I have been in exactly same boat as you are about half year ago. My archive drive failed and I have lost about five years worth of priceless data. As of today I can't find any company which is able to retrieve the information. My problem is a mechanical failure: The drive will start spinning, then click a few times and that's it...
I am still feeling the impact of the lost information and I would appreciate if you keep me posted on the "Toronto experts". If they can help you they might be able to help me as well....
Good luck!
