@lakotaubp its 128 GB, formatted as fat32 (vfat).
I haven't gotten the external drives manager to detect the card yet which is a shame.
I made two little scripts and placed them in the home directory to mount and unmount the card under /media/phablet/<sdcardlabel>, then run them as needed in terminal (I don't know how to execute bash scripts by touch from file explorer). I also am unsure how to automatically run scripts as root at startup, but oh well.
The sd card now shows up under file explorer (once the program is closed and opened again).
The first: mount_sd.sh
#!/bin/bash
# run as superuser
# Create mount location variable
mntloc=/media/${SUDO_USER:-$(whoami)}/$(lsblk -I 179 -o LABEL | tail -n 1)
# Make a mount folder, hopefully MAJOR id stays 179
mkdir -p $mntloc
# Mount the sdcard!
mount /dev/mmcblk0p1 $mntloc -o uid=32011
And the second: umount_sd.sh
#!/bin/bash
# run as superuser
# Create mount location variable
mntloc=/media/${SUDO_USER:-$(whoami)}/$(lsblk -I 179 -o LABEL | tail -n 1)
# Unmount the sdcard!
umount $mntloc
Note that I'm assuming there is only one inserted sd card which is why I can use tail to get the label. Also, I assumed the MAJOR id is 179...I don't know if this will be static across other phones or even over time, but I found it with lsblk | grep mmc and copied the MAJ column.
