I've tried both a 2.5" SATA drive as well as a 2.5" ide drive, both using a usb adapter and although I can format them fine with WBFS none of the usb loaders are recognizing the drives. I tried a segate 1.5TB 3.5" (with external power) drive and it seems to work without issue. I don't really want to use this big drive for this purpose. I was hoping I could use one of my smaller, older laptop drives. Any help as to why the wii won't recognize them or what I can do to get them working?
