I've just bought this adapter (USB2 -> IDE/SATA 2.5/3.5) for few euros: And it works very well, no problem with ISO Loader. I would like to feed my 2.5 sata hdd. The adapter comes with power supply for 3.5 drives but I would like to get rid of it and get the power from Wii adapter. Hdd consumption is 700 mA, and it would need 12V and 5V. Any idea?
