I had a couple of problems with having to reset my device so it could read the sd card before.  I like to save any applications I can to it to save room on my device.  Worked great for a couple of months after that.  Then since yesterday, it just stopped reading and started saying damaged card and try to format.  I formatted it, and it still won't read the sd card.  This was a horrible waste of my money.  I am very upset.
