Cannot see Micro SD card in Gparted

Booting into System Rescue CD to make some space at the end of a Micro SD card with a Linux partition on it. I plug the Micro SD card into a Micro to SD card adaptor, then into the SD card slot in side of laptop.

Once booted fdisk -l shows it is visible to the kernel, but Gparted will only show me the inbuilt hard drive.

What is going on?
