Finally got my Wii U a couple days ago and I finally got around to softmodding it. I used smashstack to install the homebrew channel and then used this guide for the ios's. I'm using the same SD card from my Wii, so I already had my favorite USB loaders already ready to go. Here's where my problem came in. When I use USB port 0 (The only one I'm supposed to use) my harddrive makes a quite audible clicking noise. At first I thought it was just my harddrive failing, so I went and tried my brothers Wii game harddrive, and the same thing happened; it the drive starts spinning, but before it get to full speed, it just stops and clicks, then repeats. Neither of them do it in any of the other USB slots on the Wii U or my computer. My assumption is that that USB port isn't giving enough power. Through more testing I've concluded that I can't use that specific USB port on the Wii U side either; the same thing happens. Any help or advice would be greatly appreciated, thank you.
