I have a 32GB micro SD memory card for my new iphone. I did start having some stability issues where the phone would shut down a couple times a day. I took the card out, set my phone back to the factory settings and the phone is fine. But my problem is now that I cannot get the 32gb card to reformat so I can use it in some other device. I have tried a couple different computers, multiple different card readers and even other devices to try to format this card and it will not format. How to reformat a Sandisk 32gb Micro SD.card?
