Ok, so originally I soft-modded my wii back before the twilight princess hack stopped working. I got my hard drive working with WBFS and holds many games now. It works with my wii. Then my friend got a wii, and she wanted it soft modded. So we did that, and her hard drive works for her wii almost as well as mine works for my wii. Only downside of hers is, it actually matters on her wii which side the USB chord goes in. On mine it doesn't. So I figured, all I need to bring to her house to play off of my hard drive is the USB chord for the hard drive, the AC adaptor for the hard drive, and the hard drive itself. (I also brought the SD card I use. Both our hard drives are 500gbs with 100gbs partitioned in WBFS. Both our hard drives are "My Book" (the same brand, different models, same capacity) Both our Wii's are 3.2 firmware. Only difference is, because she bought it on E-Bay (i told her not to), is, her wii is 3.2E and i'm 3.2U. i'm on IOS 36 v 9, she's on IOS 38 v 14. I used to be on IOS 36 v 10, but it made my game freeze. So I went down. I innitially set her up on IOS 36 v 9, but had to bump her up cause her games kept freezing too. Other then that, I recently did IOS 53 and IOS 55 both as wads. On my wii I have 60 and 61 (I think.....those are the ones for the shop channel, right?). I cant think of any other differences......My loaders on my SD card work for her hard drive, but not mine. If I try at home, no problems. I also have no clue what the guy before us did, because it came WITH the homebrew channel pre-installed. Its also not a LU64 serial number.
