I plugged it on my mac at 7:30 and it was I even got to watch video from it. Then at about 11:00 I plugged it in again to save a movie but it wasn’t showing up on time machine, my desktop or finder. I went to WD utilities on my MAC it was showing up and it was showing up on disk utilities too. Whats happening please help. As of right now i am repairing the disk on disk utilities.
