So my External HDD is not showing up in "Computer" but i can see it in "Device manager". I looked on the internet how to solve that and a lot of people say that i should change my Hard Drive letter and when i got to "Computer Manager" and right click on the drive the "Change Drive Letter and Paths..." it is in grey and i cant click it. I tried to run "Computer Management" as an Administrator but that doesn't solve the problem. Any help is appreciated.
