When I format an external drive with the "Mac OS Extended (Journaled, Encrypted)" setting in Disk Utility, and set a password, I'm supposedly encrypting the entire drive.
But what does this mean, and how exactly does it work?
When I open a file on the drive, what exactly happens? Is the file read into memory only? Is some other unencrypted stuff written out to the drive temporarily?
What happens when I prematurely shut down my drive (by unplugging the power cord). Does some unencrypted data remain on the drive then?
