Wii intermittently recognizes USB powered external HDD
So I ran out of space on my HDD and purchased a new one that is physically smaller and USB powered. It's the Seagate Freeagent GoFlex 1TB. I'm now having intermittent problems with it seeing the HDD. Actually, it probably only work 30% of the time. I've tried reconfiging the USB HDD in the options but it doesn't ever help. I also just bought the same HDD for my brother's Wii and same problem with his. Any suggestions? Seems I have to completely reboot the system fresh each time and then it will work. Thanks
PS, I'm using ver 70 Configurable USB Loader.
