External drive "unavailable" why when i check control panel > hardware and sound > devices and printers > usb combo 1394 (my external hard drive) am i getting information telling me that the computer detects the external hard drive, but that it's unavailable?. Fix usb flash drive does not detect or cant access files on it..
