I have an external hard drive which carries all my most precious files (some are backed up on a second hard drive, but not terribly recently).
I decided to "encrypt" this hard drive (which I immediately regretted), and now the drive won't open. I know the password, but once it's entered, it says that the drive can't be recognized, giving me the options to "Initialize..., Ignore, or Eject".
I then run Disk Utility First Aid, which says that "Problems were found with the partition map which might prevent booting."
Please tell me there is something I can do to recover my data.
