@fumoh A gentle cleaning + ddrescue in direct mode, multiple passes with the mapfile to keep track of which blocks were read vs not did most of the heavy lifting.

Piece of clear tape over a particularily damaged area on the label side that flaked the reflective material got it up to 99.99%, and after 3 days, I decided that was as good as it was gonna get.

I could have tried it in a different drive, too
