I am still recieving the ret 0 error randomly with my WD mybook750 i had to install ciosrev13b to get it to even realize anything was plugged into the usb slots.
Ive gotten 1 or 2 of my games to work using a thumb drive but even that seems to corrupt. constant ret 0 sometimes freeze sometimes reset.
Thanks for any pointers anyone can give me ive been searching for 2 days now.
