My DVR39 bit the dust. Have tried a new powersupply and get the same clicking sound as I did with my old power suppy. The drive will spin if I disconnect the white cable from the power supply to the main board. So I am assuming that the main board is dead because when I plugg it back in nothing will power up and I just hear the clicking from the power supply. So if I get an old DVR 40 that a friend has can I put my upgraded and hacked drive from my DVR39 into the DVR40 or will I need to redo the drive as one for a DVR40?
