    HDVR2 issue

    I have a hughes HDVR2 that recently started a reboot loop. It would get all the way to live TV and then within 30 seconds the unit would reboot. I thought maybe it was a hard drive issue, so I ran various diagnostics on the drive (which have never failed to identify a bad drive in the past) and this drive passed. just to be safe, I used dd to duplicate the drive to another drive I had to test. The copy completed successfully, but when I put the drive into the HDVR2, all I got was a tick-tick-tick of the head seeking (to me a sure sign this copied drive is bad).

    My questions are these:
    Could the reboot loop I describe be indicative of a power supply going bad?
    Could a power supply going bad trigger a potentially marginal drive into failing - I put this drive back into the computer that I did the copy on and I got the same sickening sound...

    What should the voltages coming out of the disk power connector be?

    Thanks in advance...

    That really does sound like a bad drive. Since the new drive clicked, that's likely bad hardware - there's no way bad software can make a head click like that.

    You should try a "replace" kit:

      I think you misunderstood my question, let me try to explain it again.

      The HDVR2 had a Hitachi 250 GB drive in it.
      • A couple of days ago it started a reboot loop. It would get all the way to showing live tv, then within a few seconds it would reboot.
      • My first thought was that the Hitachi drive is failing.
      • I have a Seagate 250GB drive that was not being used for anything, so I used the linux dd_rescue command to duplicate the contents of the Hitachi drive onto the Seagate drive.
      • That operation completed successfully.
      • I the took the Seagate drive and put it into the HDVR2.
      • When I powered the TiVo, the Seagate drive started clicking - a sound I know indicates drive failure.
      • If I put the Hitachi drive back in the tivo, the drive powers up fine.
      • If I put the Seagate drive into the computer used to do the copy, it still clicks.


      I know power supplies that are failing can cause any number of "bizarre" behaviors.

      My main question is related to the power supply:

      Could the reboot loop be caused by a failing power supply?
      Also, is it possible that a failing power supply could cause a marginal drive (the Seagate in my case) to fail like it did.

        Yes, all of those things are possible. Equally, though, the Seagate drive failure could have been a coincidence if it was on its last legs anyway. The only true test would be to try a known working drive, with known good software (not a copy of your possibly corrupt/bad Hitachi) and/or a new power supply.
