This is a response to Dan's comments:
The disk is a standard 3.5" disk, not a 2.5" disk and there are no obvious height issues.
If you remove the disk, you *can* use a hard drive dock or hard disk enclosure to attach it externally and image, clone, or copy the data off. I'm currently copying my client's data off it. And I've done the same with my own Time Capsule.
There doesn't seem to be anything special about it at all.
