g drive as 'not mounted'

I am in disk utility seeing that my G drive is 'not mounted'. I am unable to see it on the desktop, finder or sidebar. I ran first aid and it failed (check exit code 8). I have not traveled or upgraded anything in my systems so it seems unwarranted and sudden.

The G drive is in grey and signifying that it has none of my data on it. what are my options and last resorts?
