I'm pretty savvy but this has me stumped. I can load iso from wii using usbloader 1.5 but not from PC. I tried all the GUIwbfs pc loaders and none work. I get a few seconds of transfer and a bogus files copied successfully dialogue. I'm thinking it must be a hardware problem maybe... but then why would it work on wii but not pc? I'm loading it on a dual sata enclosure. I'm thinking that the problem. I've got another enclosure I can try. I'll keep trying different tests and report back.
