I got a Sony Xperia M for Christmas and a 64gb Micro SD HC card to go with it, but whenever I put music on the card (either manually or through the phone's MEDIAGO software), I always get one of several errors (either the card denies files entirely by saying the device is 'disconnected or not responsive', or if I do get the music on they sound distorted/glitchy and only last about 2-5 seconds, sometimes they don't play at all). I've established the problem is with the card because music put straight on to the phone's internal memory plays fine, so I'd like to know if there's a reason the card can't handle it and if it's fixable, or if it's basically just fucked.
