Prepare Time Capsule for shipping

I am moving and I have an AirPort Time Capsule (3 TB) with a magnetic disk drive. Do I have to do anything special to park the hard drive so that it doesn't get damaged during shipping?

It will be in a box along with other items that will be shipped by air freight. I will make sure it is physically protected (bubble wrap, etc.) to minimize the bumps.

But as far as I can tell, there's not even a way to turn it off other than unplugging it.
