FREECOMII 250 GB USB HARD DRIVE. I HAVE THE FREECOMII 250 GB USB HARD DRIVE. WHEN I TRIED TO PLUG

Question

I HAVE THE FREECOMII 250 GB USB HARD DRIVE. WHEN I TRIED TO PLUG IT IN MY I BOOK IT JUST DOESNT BRING THE ICON OF THE HARD DRIVE UP. I TRIED IT ON A PC AS WELL AND IT JUST DOESNT SEEM TO RECOGNISE IT AT ALL. I ALSO CHANGED THE USB WIRE JUST IN CASE THAT WAS THE PROBLEM AND STILL NOTHING HAS CHANGED. IF YOU CAN TELL ME WHAT TO DO I WOULD BE MOST GREATFUL. THANK YOU
