Access can't seem to figure the problem out. every time i try to plug it into my mac mini it says its drawing to much power and won't work . i have tried unplugging everything and it still won't work. i got the same notice on my macbook pro but it was still recognized. has anyone had this problem? i have a project i am suppose to be working on and i am very frustrated. if anyone has any idea how to fix this please contact me . thank you
