External Hard Drive not being recognised - Macbook Air M1

Hey,

I've recently bought a refurbished Macbook Air M1. After successfully reformatting my SeaGate 2TB external drive to be compatible in order to read off of and write onto, I stupidly hard-unplugged the drive.

Upon plugging it back in, the hard drive doesn't seem to be recognised at all... Not in finder, not in disk utility.

I have tried a variety of prompts on the terminal to mount, unmount, etc. All of which appeared to work in terminal, yet still not showing up on finder or disk utility.

Have I damaged the drive? Or has MacOS run fsck on the drive, if so can this be undone?

Thank you!
