Installer Can't Create Partition

I am trying to install Manjaro Openbox from a USB stick on an Asus X200CA laptop, using Manjaro's built in installer Calamares. I have tried different ISO downloads written to different USB sticks but I keep getting this message:

Installation Failed
The installer failed to create a partition table on HGST545050A7E680
---------------
Create a new partition table (type: gpt) on 'dev/sda'
--------------------
Job: Create new partition table on device "/dev/sda'
-------------------
Command: sfdisk /dev/sda

Any advice on how to resolve this?
