Whenever I get these cards, the first thing I do is connect it to my Windows 7 or 8 computers, and run this program to format it to FAT32.  Here's the link to the free program:[...]Many phones, cameras and tablets, need the card to be in FAT32 format, and sadly, it's not an option in Windows these days.  You can select NTFS or exFAT, but no option for FAT32 when it comes to this card.Using that program, you can format the card, then load it with whatever music or videos, and the card will work fine in your device.The 4 cards I have have never failed me in the past year, recommended :)
