Windows 8 EXTERNAL HARD DRIVE -> Cant select "Change drive letter and paths"

[Prestigebumps1]

I tried to change the drive letter because it wont appear, but it didnt work. I have tried the CMD method with the volumes but the volume did not show up. All I know is that its a G-Technology hard drive. I tried formatting it to NTFS but that wont work. Basically I tried everything and nothing works. P.S The drive is Disk1

Hi

It would help if you could show a screen capture of the Disk Management Window.
It would make it easier for people to see what is going on.
