I was helping my friend out earlier, showing her how to use the sd card on her camera to upload photos using the sd card usb adapter with my own sd card outta my phone. Since then I've been getting a notification saying,"Preparing sd card: Checking for errors." I've since shut down my phone several times, and checked the sd card under the battery casing. And it still doesn't work. Could I have nuked my sd card doing this? I did a search on sd cards, but couldn't find no tutorial or anything on the subject of how to insert an sd card. thanks!
