My Tivo HD has started making a squeaking noise. More recently I'm experiencing enough pixelation to make most shows unwatchable. I have TWC - its worked fine for years. I decided its likely the hard drive causing the issue so I purchased a new drive and used winmfs to create a new 1TB drive (I had upgraded to a 1TB around 5 years ago) and installed that. The noise and pixelation is exactly the same. I read that the noise could be from the fan, so I've tried stopping the fan with a toothpick. It's not the fan. I recorded the sound. https://www.dropbox.com/s/n4eytr74kfcye6m/TiVo sound.m4a Before I throw in the towel on this I want to check with the experts.
