I have a 1 gb sandisk micro sd card that i use to transfer music from my computer to my phone. It used to work fine without any problems. Now when I want to scan the memory card for music in my phone, it instantly freezes. Is it because I add too many songs at once? I only tried adding like 28 songs and it froze. When I added 8 songs instead, it only added 5 before freezing. Why is this?
