So I recently got a 16gb SD card. I formatted it in FAT32 and then copied the contents of my old memory card to it. When I put it in my phone all I get is errors. The phone cannot modify the content on it. I can read from it with my file manager app for a period of time, but sometimes I just cannot. I was able to rename a folder and delete a folder, but sometimes I can't. I can't make a new folder on it. When I use an application the access the SD card it just freezes up. I've tried unmounting and mounting it again, also erasing all data from the phone, nothing has worked. Any ideas?
