I have a soft-modded 3.4U Wii, a friend's NAND, but not BootMii on my system. But here's the weird part - the cause. I have MPlayer on my Wii, and I have it set up to use my 7.1 surround system, so I wanted to watch some movies through it instead of using my laptop and only getting stereo sound. So I moved the .avi and .mkv movies that I wanted onto my external Western Digital Passport (120GB, takes power from the USB port), and plugged it into my Wii. It instantly froze. I tried restarting it (it freezes a lot when I try new things, and restarting has always fixed it before.), but it began to behave like a low-level brick. I could turn it on from the controller or the power button, but it wouldn't display the warning screen, or allow the Wii remote to connect. But now it gets weirder. It was really late when I tried this, and I was in a bit of a panic, so I unplugged it and went to bed, hoping that it was just an issue with the RAM, and a total void would fix it. Well, it did. The next day I plugged it back in, started it up, and everything worked fine. I played for several hours, assuming that whatever had caused the problem went away. The next time I tried to start it, however, I got the same black screen. So I unplugged it overnight again, and low-and-behold, it worked. Again. The next time I started it, it failed again. HBC works fine when it starts, so I assume I could install BootMii without an issue. However, this strange behaviour somewhat suggests that there may be a damaged solder connection or something, and the power draw from the external drive caused it to finally give way. On a side note, I always had the drive formatted as FAT32 because the computers at school preferred it, and it was my only means of transferring data. However, as you all know, FAT is wrought with horrible corruption and is easily damaged. After I graduated and became incredibly frustrated with this, I backed up the data and reformatted the drive in HFS+ (Apple's standard format). So what could have caused the failure? What could I do to fix it? Thanks for your help, -Finn EDIT On a whim I removed the battery, in case it was holding some tiny tidbit of data that shouldn't be there. No luck.
