Lock suddenly appears on external hard drive
I was preparing to do a back up. Suddenly, a small lock appeared on my second volume on my 13" MacBook Pro (Sept. 2012) and then locks appeared on all three volumes of my external backup drive (4T G-Drive).
I have been trying to fix this since Friday, 25 Nov. 2016. I have tried using another computer with a different OS to no avail.
Is this a good question?
