Hello,

See if the following link helps

Red Power Light When External HD Attached & Cannot Access It

I have an EX2 and want to connect a 1TB Toshiba external hard drive to it. I plug it in the back and the power light which was blue on the EX2 turns red and I cannot see where to access the files on it. I have the USB access setting in the GUI set to on, I’m assuming the red light is some kind of warning light to say its not working correctly but I cant see what else to do. Cheers
