I am now testing SD card. However, it showed that "Initializing sD card...initialization failed". What should I do to sovle this issue?
By the way, this is new SD card, I am not sure if I need to format it before insert (I did not do that). And my laptop system is Win 11, is that ok?
Figure shows my Micro SD card and Micro SD Card Module. And I use Arduino UNO R3.
