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
