lol, I knew you were going to come back and ask that
. [I've never had to do it, but I don't think its that hard].
Well, make sure you've got your content backed-up first.
Then, go to
Settings and then
Storage.
From here, you'll have to do the "
Unmount SD card" first before you can do the "
Format SD card" (the "
Format SD card" option will be greyed-out until you unmount it).
Then select "
Format SD card"...not sure if/what it will ask you next since I don't really want to format my card, lol.
After the format completes, just do the "
Mount SD card" and restore you files.
Hope that helps. Good luck!
