Excellent toolkit and live desktop distro that is smooth and lightweight. Thoughtful compilation of disk recovery and system tools, with some custom scripts. Slackware based. Worth paying for but the annual subscription is pricey and the one-time downloads quickly go out of date from a security perspective.
I wish it was free. It was free. But not any more. But this one is a gotta have. I have gotten myself out of some many jams I can't tell you. The grub repair is worth the money, works and it fast. Not terminal or scripts or anything like that. And it will allow you to grab stuff of a HD even if that HD will not boot.
You need this one in your tool bag. Pay Patrick the $$$ and get it.
