Googled my way to this topic, after my i9300 ate its second SDHC card. First one was a Class 10 8GB Sandisk and the second was Class 10 32GB Samsung (lololol). Tried to connect the second one to my PC with four different micro SD card readers, and it's like it's not even there. Used Poweramp to play music from both of them, and I've been running WanamLite if that matters.
