Not necessarily.

2. Until decrypted, a TrueCrypt partition/device appears to consist of nothing more than random data (it does not contain any kind of “signature”).

Huh — I was unaware that TrueCrypt has plausible deniability by default. I know it's possible to set up plausible deniability, but with LUKS that takes extra steps, and I assumed the same was true of other disk encryption schemes.
Usually when you encrypt a drive there's a telltale header, so the disks wouldn't be "seemingly encrypted" at all — and wiping disks clean with noise isn't especially uncommon. It's as plausibly-deniable as it gets, and it'd certainly fly in court.
