I am going to get a new external harddrive for my computer. I currently Have this one. How does this particular model work on the Wii? I looked in the compatibly page and I couldn't find my exact one. I did see that some WD's have problems but I saw that the Western Digital My Passport Essential 2.5" 500GB is just about the best you can get. My drive seems to be the same except for the fact that its the bigger version. I'd imagine mine will work but i dont know. I can't test it because I have almost 500 gigs of data on it. When i get my new one, I will transfer it over and use the old one for my wii.
