Macbook Pro early 2013, Ubuntu 14.04 (latest updates as of March 30th 2016). Everything works in OSX. A regular 2GB SD card worked in Ubuntu.
When I plug it in it shows up in /dev as mmcblk0.
When I attempt to mount it:
domenic@mac:/dev$ sudo mount -t exfat mmcblk0 /media/domenic/thing/ [sudo] password for domenic: FUSE exfat 1.0.1 ERROR: exFAT file system is not found.
But I have fuse installed:
domenic@mac:/dev$ sudo apt-get install exfat-fuse Reading package lists... Done Building dependency tree Reading state information... Done exfat-fuse is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 7 not upgraded.
I have also tried a variety of file-system formats, and I have also tried varying sizes of disk partitions to eliminate these cases.
Here is the output for fdisk -l:
domenic@mac:/dev$ sudo fdisk -l [sudo] password for domenic: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.
