Picked up a 64gb SDXC Kingston card and thought I would share how I got it mounted and working.
After a bit of research, many people were saying that the card should work out of the box, or reformat to NTFS first. Or just stick it in the phone, go to storage, and format it from there. Didn't work for me. I'm rooted, so booted into custom recovery tried to 'mount & format' from there; again no go.
I run Linux (openSUSE) on my PC, put the card in the reader, wouldn't mount. Turns out the default file system exFat32 is quite picky about what can a can't read it.
So this is the fix that worked for me:
You need access to a Windows 7 PC (Really couldn't get it to work with Vista)
Download SDFormater from here:
https://www.sdcard.org/downloads/formatter_4/
This will reset the card to the default file structure.
Now, we need the card in a file structure the S3 will read, namely FAT32; the problem with this is Windows can only see / format 32gb of FAT32. You will now need MiniTool Partition Wizard from here:
MiniTool Partition Wizard Home Edition - CNET Download.com
Install it to windows and run.
Your card will now show as F:/ (Or whatever drive it's in)
Right click on it in the window and select 'reformat'. Choose FAT32. Click Apply on the menu bar and it will reformat all 64gb.
You should now be good to go!!
