I formatted my Passport Ultra as advised when I got it in September. It did a Time Machine back up of my computer at the at time.
Now it brings up the ‘WD Drive Utilities’ app and i put in my password but that as far as it’ll go. it just closes at that point. It won’t back up at all.
Im using a almost 6 year old Mac desktop running OS X El Capitan version 10.11.2
