My 64gb micro sd sandisk card was working perfectly earlier today, and had been working perfectly for months, when, out of nowhere, today, my phone is notificating me saying "SD Card not inserted". The only option it gives me is to "Forget", which means all the data it contains will be lost forever. I had nearly 30gb of music (118 albums) and pictures there. I've faced problems with these sd cards before, but this is simply unfair and nonsensical. Can I get some help please?
