@admin i understand that its just within this slot would wear out, i have a workaround well 2 in fact and thats to use the micro sd to sd adapter and insert the card then turn on the printer. or using another marlin software builld which is marlin 2.01 bugfix 2020-11-13 as this has a feature in which you can remove the sd card by selecting change media. i do hope creality can include these features into their future firmware builds to overcome these issues.
