What do you say?" But you are testing R1_ERASE_PARAM in CMD35? Honestly, I don't really know, just want to verify that you changed your mind.

Check for erase specific R1 errors so e.g. an OOR erase is not reported as successful when it never executed. There could be checks for more error bits but R1_ERASE_SEQ_ERROR on CMD38 should catch all that are reported by hardware anyway.
