I just setup a new 8TB external drive to be used as a Time Machine backup. When setting it up through Time Machine I turned on encryption. After the backup was complete, around 17 hours or so, the encryption progress bar did not seem to be moving much and it had a long way to go...I just ejected the drive and remounted it and it prompted me for a password. Did it actually encrypt it? Is there a way to determine if the drive is encrypted? Thanks.
