Where did Sector 16/17 come from when I run a hf mf chk they don’t show up

The dump file shows partial but all the keys are there, cloning the dump to a new card, only shows 15 sectors not 17 and all the A keys are totally wrong matching sectors 14/15 in all sectors except 0,1, 2, 3.

I am trying to test on this card that came with the proxmark from dangerousthings, before I try it on the ring, which is a totally different animal.

Anytime i try to write to the wring I get so many errors on the A Keys.
Any help would be great

Sector 16 and 17 are where the originality signature is stored. Magic tags don’t have them, and in most (not all) cases you don’t need them.
