The finding of a second keystore on your honeypot drive will totally destroy any attempt at plausible deniability. Or will it?
Not necessarily. You could create a false keystore, one with a very long (and different) passphrase to suggest you have been attempting to create a hidden drive but without success. You can prove this is feasible by demonstrating this keyfile cannot create a hidden operating system (naturally, only after you have already proven this to yourself with this particular keyfile). Ostensibly you have no idea why DCPP refuses to cooperate, but the passphrase opens the keystore, proving it is correct. That is superb plausible deniability.
