I'm having trouble accessing my Samsung 128GB micro SDXC card.
My Lenovo Legion Y520 laptop is running dual boot with Windows 10 and Manjaro KDE.
Windows recognises and reads the card without problems.
On Manjaro the card is recognised in the partition manager but it says that "No valid partition table was found on this device".
I also tried to mount it manually:
sudo mount /dev/mmcblk0 /mnt/sdcard/ mount: /mnt/sdcard: can't read superblock on /dev/mmcblk0.
The card is formatted in ExFat and I do have exfat-utils installed.
The laptop doesn't have a micro sd card reader but it does have a normal sd card reader so I'm using a micro sd to sd adapter.
