Help Blank SD card or unsupported file system

Try pulling the micro SD card from the phone, inserting it into s SD card adapter, and into the SD card reader on your computer (assuming that your computer has one). If the computer can read the card without issue but your phone can't then it's likely an indication of a bad card reader in the card. If your computer has the same issues reading the card then you may have a bad card. You can try formatting the card on your computer but you'll likely need to format it again once you re-install it on your phone.

If you've got a spare micro SD card you might want to try installing that in the phone to see if the phone can read/write to it. If it can then I think you'll have some good ammunition to justify asking Verizon to replace your faulty SD card. Whether or not they'll do that is another matter entirely...
