So last night, I was setting up a new look on my phone. Nothing drastic, just a new theme and icons. I installed Beautiful Widgets and then got everything set up the way I liked. Went to bed and everything was fine. Today, I noticed that my sd card was unmounted and could be safely removed. I tried to remount it manually in settings, still said it was unmounted. I rebooted a few times, same thing. I pulled the battery and took my card out, stuck it back in and rebooted, same thing. I don't know whats going on. Anyone got any ideas? I'm running the newest version of MIUI.
