I just replaced the noisy hard drive in my Tivo Series 3 with another drive. Unfortunately it is also quite noisy. There is a constant tapping sound coming from it, that is audible from 10 feet away. The replacement drive might have been a NOS (new old stock) or 'refurbished' drive. I am not sure, but I ran some diagnostics when I first got it and it said '0 hours' usage. What are some brand new hard drives that will work in a Series 3?
