If you use nintendont then you know you can't have more than hard drive plugged in at the same time. For a while I've had two hard drives sitting next to my Wii; one with actual Wii games and the other with gamecube games. I was content with physically switching usb cable out etc. But it's a pain when the console is tucked away in its spot. I came up with a basic usb switcher. Concept is simple: It's a 2 to 1 usb device with a simple tactile switch. This device runs on 3.3v but could run up to 5v. If the Wii is turned on the button has no effect, so no worries accidentally spinning one hard drive down and the other up. In the picture the led looks pretty bright, but in reality not so much. There is a pot on board so you can control the brightness to your liking. I still need to apply some double sided tape to keep the switch board in one spot (There are no components on the bottom so it lays flat.)
