I setup a new 4TB drive for Time Machine and after the first backup I right clicked on the drive and chose to encrypt it. That was almost two days ago and the progress bar for the encryption process is still not even a quarter of the way...does this sound right? It is plugged into my 2015 MacBook Pro and I need to use it though I am somewhat limited working with it while it is connected to this external drive. Is there a way to quit the encryption process? I do not see an option. Will that damage the external drive since it is in process of being encrypted? Thanks.
