Advertisements Have a S3 HD with a 5 year old 1 TB drive that's work perfectly but know the HDD is at the end of its expected life. Going to jump on this deal but would appreciate any advice from the forum. Only two people in household with two TV’s so number of tuners isn’t an issue but am always up against our current 1 TB storage. Should I just purchase a Bolt Plus or go with a 500 GB Bolt and upgrade the HDD to 2-3TB (saving about $175)? If I go with the 500 GB Bolt, will Tivo void my warranty on any non-HDD issues?
