I did wipe all things BIAB off of my drives. According to Support I broke a link that was not fixable -
As I had saved all of my online downloads from Summer when I bought 2017 Mac BIAB I just reinstalled every .dmg file. Program, Styles, Real Tracks, etc. Even without downloading all the Real Track files again it was still an 8 hour process.
I have everything running on a single 7200rpm peripheral drive and all is well.
