I replaced the hard drive in my 5 year old Roamio Pro a few weeks ago and copied over all of my shows using mfstools 3.2, specifically mfscopy. I replaced the original 3TB drive with a new 4TB drive. Everything seemed to go fine with the drive replacement, and the TiVo Service Connection was succeeding until last Thursday, a week or two after the drive replacement. It's been failing since last Thursday but I didn't realize it until tonight. I tried a reboot or two but when I force a connection, it gets to the "Loading Info" step with status "Loading...", but then errors out with "There was an error loading series data". This didn't happen before the upgrade. I have less than a week's worth of guide data left. What's wrong and how can I fix it?
