I have an encrypted hfs+ external SSD. When I plug it into my mac and, it prompts for my password, but after I enter it nothing happens.
I tried this in terminal:
I ran into this. In my case it seems the problem was the mac wanted to run a filesystem check on it. After finding the fsck process and killing it, I could then mount the drive properly.
$ ps -ef | grep fsck $ kill [pid from above]
Note: What I've provided is a standard procedure to solve most minor problems. It may not work and you should backup before doing any potentially dangerous tasks.
You could try to convert the encrypted CoreStorage device back to normal using the
revert keyword of
diskutil cs revert <LVUUID> -stdinpassphrase
with being the UUID of the logical volume. What bothers me, however, is that
diskutil cs list shows “–none–” for the
Disk parameter of the SSD logical volume...
The only time I've seen this I tried mounting it on a different Mac and it was successful. I wound up copying data from the drive and erasing / starting over.
