Faulty 16GB Micro SD Card

My suggestion if you want to protect the data but take advantage of the 1 time exchange option. Copy the data from the disk, to 2 different sources (so you are sure to have it) then get a big magnet and rub it all over the disk, on both sides. The data will be gone and you can send the disk in. Of course I do not know what anyone else woulod saay about that. When I used to have 3.5" disks, before I tossed them in the trash I used to mag wipe them, same for video tapes, etc.
