I undid it by moving to ufs :-) Couldn't. It would mark the range bad in such a way that you couldn't mark it good. It did this using sector replacement off the VTOC. This means that if you put a UFS on it without redoing the install, you would end up with the sectors remaining marked "bad". The low level format wasn't technically required, but if you did not szero the spare area and the VTOC, it would recognize this on a simple reinstall, and the sectors would remain "bad".
