Advertisements Two mornings ago, when I was getting ready to go to work, I noticed a more-prominent-than-normal hard drive reading/writing noise coming from our TiVo HD. It sounded like regular hard drive read/write noise, though, so I figured that an upgrade of some sort had been downloaded overnight and was installing itself (or something along those lines) and went on to work. That night, when we turned on the TV, we were greeted with our TVs blue screen and a "No Signal Found" message. This hasn't happened all that often, but when it has, it has always been fixed with a hard reboot of the TiVo and the WD Expander (by pulling the power cord out of both, waiting 30 seconds, plugging the power back into the WD Expander, waiting another 30 seconds, and plugging the power back into the TiVo). So, I did this, and after the interminably long bootup time of the TiVo, the intro animation started playing and I figured it was all working. But then, partway through the animation, the video and audio stuttered and skipped and froze a little bit...but it eventually got through it. However, once I was at the GUI, the background animation was noticeably jerky (and even froze for 10-20 seconds a couple times) and when we tried to bring up the Now Playing list, we got a blank screen. Fearing the worst (hard drive crash), I unplugged everything, waited a bit, and plugged it back in. Same thing...seemingly fine, but became jerky/slow/frozen partway through the intro animation. So then I unplugged everything and we had dinner, gave the kids baths, put them to bed, etc. Basically left it unplugged for about three hours. Then, when all that was done, I plugged everything back in and waited (with my fingers crossed) for the bootup to finish. It finished, and everything was fine. Animation was smooth, GUI worked as expected, Now Playing list came up fast, etc. I was puzzled, but figured it was just a random "blip" or something and we watched some recorded shows and called it a night. Fast-forward to this evening, and the same thing (almost) happened... Turned on the TV. Instead of seeing our TV's blue screen and error message, we saw the Now Playing list, but it was empty again and the GUI background animations were choppy/frozen. So, I did the hard reboot thing again, and the same thing happened as last night...it booted, got partway through the intro animation, and then became jerky/slow/frozen. After it eventually made it to the GUI, it was pretty much unresponsive (most likely just severely delayed due to whatever was slowing it down) to all remote commands and whatnot. So, I unplugged everything and we did the same dinner/baths/bed routine. After that, I plugged everything back in and it booted up fine and is currently working perfectly as I type this. So I'm back to being puzzled. At first it seemed like a hard drive problem, but now it's seeming more like a heat-related problem? At any rate, was there an update a few days ago that might have introduced this (this particular set of symptoms hasn't happened before)? Does anyone have any ideas about what might be going on? I want to narrow down the possibilities a little bit on this, because I'm hesitant to purchase a hard drive replacement only to have it turn out to be something else. Basically, I need to know whether it would be better for me to replace the drive, get a new TiVo, or what. Any ideas?
