Advertisements Apologies in advance for duplication. I also posted this on a forum where the latest reply was 2018. Not sure of protocol but hope it is ok to post it again here so it gets someone's current view: 1. Allow me to join the me too parade. I just spent the day on two different tries, neither worked. My Box is Tivo Bolt, series 6, new 12/2019. 500 Mg Hd. Software 129.7v7-USC-11-849. Spent the day on the following: Try #1: WD blue label internal 2.5" H/D - 2 T/B, Model WD208PZX, 6 GB SATA (blue label). from Amazon @ $84. After install the Tivo gets stuck on "Starting Up" screen. Several tries, each 1 hour or more. Does not "Boot" further. No change. Called W/D: Their tech thinks power supply cord might be the problem but not sure. Says send the H/D back to vendor. This one drives me nuts as the 500 drive in the Bolt is also Western Digital # WD 10 EURX63FH1Y0 (Green Label). So, i replaced the original 500 GB drive back in the Bolt and it is working fine again. Possible Fix: A post elsewhere on this forum said going back to previous software got their internal upgrade (with this exact WD 2TB Internal HD) to work. I would rather not go to the old interface. And, every time Tivo updates, would it not install the new software interface? Try #2: External H/D, 3 T/B, 7200 RPM Fantom Mega Disk USB 3.0 & eSATA connectivity. Purchased separate eSATA to eSATA cable to make the connection to the Bolt. Catch 22 - If you have been down this road, and read the forum posts, you know that the only external HDs that TIVO recommends are WD external Hard Drives. Problem: WD externals only come with USB connectivity. TIVO Bolt only recognizes (allows) eSATA connected externals. If you plug an external drive into a Bolt USB port nothing happens. Not recognized. So, off to the web where I found lots of posts here. And, also found that only the Fantom 3 T/B 7200 rpm drive has an optional eSATA port. Bought it! Don't waste your time calling TIVO for that free eSATA cable. They don't know of one free or for sale. Back to Try #2: I connected this Fantom drive with its eSata port to the eSATA port on the Bolt. Followed instructions elsewhere on this forum. Power on Fantom, with power to Bolt unplugged. Plug in Bolt and allow restart. After full restart, Bolt detects new External Drive. Do I want to set it up? Yes! But after I select "Set up" I get "Unsupported Drive", contact TIVO/External on line. That link proves to be a 404 - no such link. A Real life Catch 22! Sure could use your help! I would like to go to at least 2 T/B storage. I don't care if internal or external but my preference would be internal. Does anyone have a solution (with product recommendation) that worked for them on their BOLT?
