I tried fixing this on various computers running High Sierra, so I figured this would be the best place to ask the question.

I wanted to encrypt one of my large external hard drives - 4 TB. I should have just purchased a new drive and encrypted that then transferred files over instead, but oh well. The encryption process was going on for over 24 hours and it was stuck at 10%. Unfortunately, we lost power. Now, I am unable to mount the drive and everything on any computer locks up if I try to do something on the drive (Restarting/Shutting down is a no go after running some terminal commands on the drive). Is there any way I can get the drive back? Either reversing the encryption or something else?

Thank you!
 
Im having similar problems, in that I've a 5TB External hard drive for which I use with Time Machine. Recently done a fresh install on the Mac OS and now Time Machine only goes back one or two days. Started encrypting the HD, four days in...still going. My question is: Is it safe to unplug the HD whilst its encrypting, i.e Overnight?
