...welp used the sd card formatter tool to try and wipe this sd card...
and it disconnected somehow halfway through, so the format failed. and now windows doesn't recognise the SD card at all so if it's plugged into the reader, it doesn't detect it at all.
meaning I can't format it hahahaUHFSHasjfAHSFAS
@Nine tbh when that kind of thing happens in my experience that's usually an indicator the SD was buggered in the first place
