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???
