> Tell the authorities that you "fill your hardisk up with random data before traveling in case of theft."

And you just made yourself a suspicious person to be further questioned and searched, while probably committed an offense that could send you to jail.

But again - the point is not to lie, technically and thus avoid commiting an actual offense. If your data is important enough to you, you probably will want to consult your lawyer before attempting such a scheme :)
