    Just received this 1 TB drive. It does not work and just makes a low intermittent buzz. Case seems to be very flimsy, not solid like my other Seagate drives. Do not purchase. Will be returning it.

    This was purchased to use as a dvr recorder for a portable satellite dish. Opened the box, attached the usb cord to the satellite box and formatted it per the onscreen instructions. Does not get any easier than that. Other than being a bit pricey for what it is I have no complaints.
