I'm testing data destryoing/recovery tools to determine just how good is good enough when it comes to destroying data on a disk. I've read Peter Gutman's stuff and I've been using Dariks Boot and Nuke (wipe on a linux floppy) to destroy data. Now I need to find the world's greatest recovery utilities to see if there's any way of retreiving it. I've used a few different utilities so far, and the best one I've found is the tool that Ontrack provides on their website. Data can't hide from it, but after DBAN it sure did :-). I'm looking for something a little extra strength now... I want to make sure the ONLY way that data can be recovered involves a few trillion dollars and a clean room. These computers need to retain their hard disks, so grinding them down to fine powder or melting them into goo isn't an option, however I realize it is the most effective. Thanks! -Brian
