Advertisements I bought a 500 Gb harddisk upgrade from DVRupgrade for my DSR708 DirecTV TiVo recorder and installed it. The machine boots fine but quickly freezes at frequent irregular intervals and can only be reset by disconnecting the powercord. I believe this could be caused by the following: - The wrong software version on the harddisk bought which identifies itself as DSR7000/17 rather than DSR708 in the DVR Setup menu. - A higher current draw. The new harddisk is a WD5000AUX 500 GB drawing 5VDC 0.70A and 12VDC 0.55A per the label whereas the old harddisk is a WD800 drawing 5VDC 0.35A and 12VDC 0.50A, also per the label. I should add that the power supply in this DVR was replaced maybe three years ago, also from DVR Upgrade. The harddisk is, of course, a SATA harddisk which has an IDE adapter which may also draw some current. A third possibility, overheating, can be ruled out since I also removed the DVR cover and put a powerful fan directed at the harddisk and power supply with no effect. Last, a problem with the mother board can also be ruled out since I then put the old harddisk back in the unit and the DVR runs fine. I believe the power supply is the most likely culprit. Can it in DSR708 be replaced with one allowing higher current draw? If so, which one and where to buy? I am assuming that the new power supply I installed a few years back and purchased from DVRupgrade was an exact replacement for the original one but have no way of checking that now since the old one has long been discarded. Thank you.
