adding usb hd to SATA connector on r-24 rcvr.

Connection problem for adding an external HD to the SATA connector on the back of the R-24 receiver.. does anyone have a solution to this to connect a hard drive with only a USB connector output on it? I have two or three 1 terrabyte recorders that I have used for extra storage with dish. Speed is not a problem. USB is plenty fast enough for me as I transfer everything to the hard drive after I go to bed at night. If it takes 6 hours or more, that is no problem.
