So I recently got a 64 gb micro SD for my Kyocera Event. It is a Sandisk Ultra, the type specifically advertised as being for the event.
After first inserting it, I got this error and the event offered to format it. I did, but the error persisted. I then formatted the card in windows, first with the windows utility and then with the SD association program.
The card still does not work in my Event; I get the same error.
The card does store information from the computer with no problem. In addition, I have a 2 gb SD card that works fine in the event, so I tried to copy and paste all the data from it into the 64 gb card. The card still shows up as blank.
I thought there might be a problem with the phone's software, so I backed up and reset the phone. Still nothing.
I have to be missing something obvious. Help?

Update: I formatted the card in FAT32, and this error went away. However, the card still will not mount.

 

SanDisk advertised this card specifically for Kyocera devices like the Event.
If I partitioned it into two 32 GB pieces would it work?

 

Unfortunately, partitioning the card just made my phone stop recognizing it. I'm going to try and contact SanDisk about it, and see if they have advice.
