Cannot mount or erase external Lacie hard drive

My external hard drive stopped working (as Time Machine backup) and now it will not mount or even let me erase. It only shows up in Disk Utility and I can run first aid when I try to erase the erase button is enabled but when I click on it nothing happens. It won't mount either. Anybody have any suggestions???

MacBook Pro 15″, macOS 10.14

To rule out that the drive may have failed, have you tried connecting it to another computer to see if you can access it from there? If you don't have another device, maybe see if a friend or relative can help you out. Alternatively, you can take it to your local Apple Store or Apple Authorized Service Provider for assistance.
