Since the Lumia Black update I've been getting an error whenever I turn on my phone that says I need to reformat my SD card. Whenever I try to format it on the phone or on the computer it fails, also when trying to add files (eg. download music, pictures, etc.) they delete themselves soon after like they are reading from the temp files for a short time but not staying on the card. My card will still play stuff that is already on the card fine. I transferred all my pictures, music, and videos onto my PC for backup and tried to format it there but it failed. Then I tried to format on the phone and it failed. I tried using third party PC formatting applications which failed as well. I then noticed a hidden file on the SD Card called WPSettings.dat that is stored in a folder that is called WPSystem which is write protected. I thought maybe this is the reason it wouldn't format so I downloaded various applications that claim to remove write protection so I could delete the file but none of them worked.
My card is a SanDisk SDXC Class 10 64gb card that is half full.
Please help. I'd like to fix it before Windows Phone 8.1.
