Hi Everyone. I Am Using Samsung Galaxy S5830. Yesterday, I Was Using It And Suddenly An Alert Popped Up. That Said, Format Your SD Card. I Attached It With My Laptop Using Card Reader Device. The Same Problem Was There. A Box Popped Up And It Says, "You need to format the disk in drive F: before you can use it". I Even Tried To Format It But Was Unable To Format It. I Really Don't Want To Lose My Data. Need Your Help Guys. Thanks In Advance.
