Gotcha - I wasn't sure the amount that "should" take up.
I re-seated the cables to the drive twice, and rebuilt the drive on-top of itself and the problem persists.
I will try swapping cables with another drive tomorrow (I use breakout cables like this: https://www.amazon.com/gp/product/B013G4FEGG/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1), and also read somewhere that the crc errors that I am seeing are typically (almost always) cable related.
I have attached a new diagnostics and SMART report from the rebuild as well - if this adds anything. I'm just trying to determine if it's a cable issue, a drive that needs replaced, or something else at this point.
