Advertisements Are you sure 2 TB is enough for you? Have you checked on the warranty with Western Digital (wdc.com)? It may have expired long ago, and they do not make these anymore. If you are not worried about the content on the older drive, just swap out the old drive for the new and it would be a newer Tivo. You would need to re-pair the cable card though. I have used a WD Red 4TB WD40EFRX in my Roamio basic about 4 years ago and is still running strong. It is also more quiet then the Green drives.
