Well, I'm taking a big step back to figure out exactly how FileVault, Disk Utility (and diskutil), Keychain (and its Access Control) work. I'm at a loss at the moment.

Ejecting doesn't appear to relock the volume. And when locked (how?) Disk Utility and SD can't mount it, despite Keychain.

If ejecting would consistently lock the drive and Keychain's Access Control only gives the password to applications I allow (i.e. not to malware) then I'd be good. Not seeing that right now.

Cheers
