These work great on your Wii.

I just bought a 720gb one for $110, and love it, in fact, it's plugged in right now.

I've always wondered if this hard drive has trouble at times because you don't plug it into the wall. Most HDs do this to provide extra needed power.

@evilbusdriver: 2.5" drives do not need a wall outlet because they do not draw as much power as 3.5" drives. Instead, they come with a USB cable that has 2 USB plugs on the computer side, so you simply use double USB power to drive them. You SHOULD insert both USB plugs in the computer, even though you may be able to get the drive to operate with just one.

@dcarno: The WD Passport only has 1 USB plug. I have several of them (of different variations as they've changed over the years) and have never had problems with them, though.
