i just picked up an airport extreme base station, fixed all of my wireless problems as far as drop outs and disconnects. i just plugged in a 250 gig external usb drive to the airport and it wont mount on my desktop. the disk is recognized in the airport utility but not through airport DISK utility. how can i fix this problem? leopard 5.2 and firmware 7.2.1 update* so now i can manually connect to it but it still wont mount even when i connect to the disk using the finder and typing in the ip to the router and putting my password in.
