Be careful in countries like UK which have laws requiring the decryption of any data they find. There are people sitting in jail because they couldn't decrypt the "random noise" on their computers.
Fair warning; any links to specific cases (not the law itself)?

No, there isn't.
There literally are not. Anyone competent enough to be an expert witness will be able to plainly explain to everyone else how statistical analysis obviously delinates the difference between truly random noise and an encrypted volume.
This is exactly the point. If storing random data was the norm (formatting utilities would offer it) then it would be hard to make a case against it.
And it actually _does_ make sense for formatting utilities to offer it, as this is a good way to ensure that data is really gone after formatting (writing all 0s or all 1s could leave information at the physical layer; and any intermediate layer could not compress random data much so the data must be overwritten).
