I’d get a new drive. Install a sane os and need tool and use that. They should be cheap these days. Put the old one in a safe place in case you need something from it. When you find it years on and notice that there was nothing important there after all, recycle it. That’s a much safer approach.
A personal wiki or a text file, depending on the place. Would be nice to have some compact non invasive ticket system, but I’ve never seen one.
I’ve used literal card decks and GTDish pen and paper systems when there was more demanding need on tracking things. They’re effective.
