Pop_OS won't detect an external SSD

I plug in an external 1TB Crucial X8 portable SSD via USB but the OS can't detect it. I used to use the SSD as external storage for a PS4. I can plug it into my phone and a Chromebook and both detect the drive automatically. I've tried reformatting the drive via my phone and the Chromebook, I have connected it via 3 different USB ports, and tried another USB cable, all with no success.

What else can I try?
