128gb SDXC micro sd problem! Help me find out what happened to it please!

Hello!

Thanks for the quick reply, and excuse this late reply

I skipped step 1, as I literally got the micro sd out of the box and inserted it directly in my tablet. So there’s no chance that it needed its pins cleaned.

I followed with step 2, then at step 3 it seemed to work slightly better. Though I’d rather format for complete peace of mind.

What options should I select in the program you provided in order to format a sandisk 128gb SDXC Class 10/UHS-1 micro sd correctly?

Attending your response with most sincere gratitude.
