I have a question about the SA with the 82-00515-5 controller. The SA is at the start of the page and periodically ends (see pic). How does this affect the LBN in the markers table as there is data in the area above the SA. Or is that take into consideration in the build somewhere? And yes I know there are bit errors

SA looks OK here, maybe you have empty blocks which is why some XOR pattern is visible, but SA looks OK to me. LBN is at one of two positions (possibly reversed), and header is at first byte of SA. Probably structure is 14_2048_146 or 14_2048_230 repeated until end of page? |

Many thanks. |
