I'm having an issue where my SD card isn't being recognised. I've tried it in my (2013) Macbook and my electronic drum module. It's not recognising on either device which is telling me there's an issue with the card itself. Is there something I should be doing? The card has a little lock catch on the left which is set correctly. I've pretty much exhausted looking round on the internet and come to the conclusion it's the card itself which is shit. I bought it last January, obviously accepted it wouldn't work and just didn't bother with it since.
FWIW, it's this one.
