I discovered this when I had a consistency issue with a couple of files on the drive and ran chkdsk. Unfortunately, that saved password doesn’t seem to work.
Fortunately for me, I also set the drive to auto-unlock for my user account on my computer and I’m not completely locked out of the drive. When I created my password I saved it in my password manager. I have a situation that is a bit different from your standard “I forgot my password” issue.
