> Disk encryption prevents revealing the plaintext of files on disk, but you can still observe their ciphertext changing when the file changes. If the duress command causes different files to be modified compared to a normal login, then that can be detected by comparing to the original disk image, even though the actual modifications performed are hidden by the encryption. How would they even be able to determine which files are modified? If we're talking full disk encryption here, you can't tell which files are being accessed/modified, just locations on disk. Without metadata to map blocks to objects they're flying blind.
