How Do I reformat a LaCie Rugged All-Terrain Hard Disk?
I was using the LaCie Rugged All-Terrain Hard Disk to back up my MacBook Pro. It has stopped responding to Time machine. Doesn't seem to recognize it when I plug it in. I've replaced it with a Seagate, but would like to reformat the LaCie and see if it will work. When I plug the disk into the usb port, the Mac doesn't respond to the LaCie although I can hear the LaCie. Any help would be appreciated. Thanks.
MacBook Pro, OS X El Capitan (10.11.6)
