Advertisements With my first Tivo, I got what I thought were signs of a dying hard drive: when switching channels, I got pixelated, stuttering video for 3 to 8 seconds. Sure enough, after a few weeks the hard drive went. Replaced the hard drive and all has been well ever since. Recently, my second Tivo began showing the exact same problem. Assuming the hard drive was on its way out, I preempted the problem. Bought a new hard drive, used mfstools to copy the original hard drive to the new one (copied everything, including recordings, about 37GB). Put the new drive in the Tivo, and all's well. Except all isn't well. Everything is there, all of my saved shows, and it shows increased recording time. But the pixelation and stuttering is still there when I change channels. I've switched the video to bypass the Tivo and flipped around to make sure there wasn't a problem with my cable box (perhaps with a bad or weak signal, or signal noise). No issues - channel changing works fine. This concerns me... was the hard drive not to blame after all? Or did I somehow duplicate the issue by copying the Tivo drive in its entirety? Or could it be something else?
