USB Loaders don't recognize external hd
I softmodded my Wii using Dogeggs' tutorial. I went from firmware 3.1U and upgraded to 4.0u to 4.1U. I installed USB loader gx, uloader, neogamma, and configurable usb loader. None of these recognize my external HD (iomega 500gb mdhd500u value series). I checked the compatibility list and this one has not been tested. I have cIOS rev15 and have installed hermes ios222/223 trying a combination of merged versions as well as unmerged. i am also using the usb port closest to the edge.
Any clues as to how my external can get recognized? or should i retry to softmod it? Thanks for your help!
