Want to use the exfat system on a new SDXC memory card,
This works, came from here:

exFAT is a proprietary file system developed by Microsoft, and implementing it requires accepting a very restrictive license from Microsoft. However, there is a FUSE implementation of exFAT for linux.
Since you are on a Ubuntu system, you can install the above-mentioned exFAT implementation from their PPA.

  1. Add the PPA to your sources list by running
    sudo add-apt-repository ppa:relan/exfat in your favourite terminal emulator
  2. Install the fuse-exfat and the exfat-utils packages:
    sudo apt-get update && sudo apt-get install fuse-exfat exfat-utils

Now you should be able to use the SSD

It worked instantly on my Asus Zenbook UX31 E (Mexico version)
