The only way to resolve the issue was to use the method previously provided which is to re-format the drive. It took several attempts to connect the device to a few computers, but it finally mounted and then I was able to right-click and format the drive.

I then had to do a hard reset as several of the sprint customization settings install to the storage card by default. Otherwise, you end up with multiple folders called internal storage.

Once the drive was reformated, I have not experienced any other issues with the storage using a PC or Mac.
