External HDD with True Blue question .
I have just bought the True Blue Dongle and i wanna know one thing .
When i boot the PS3 with dongle inserted at first the light on the dongle turns red and then after a few seconds it becomes green and the PS3 turns on . Then i insert my external HDD in the other USB port . I wanna know is it safe to keep the HDD and the dongle pluged in the PS3 at the same time and then boot the PS3 or i just have to wait for the PS3 to turn on first then inserst the HDD and thanks .
