Double checked similar threads. My problem wasn't among them. Background: Came home a couple days ago and discovered we had a power outage while I was out. Surge protectors and UPS devices were reset and all was well aside from my Tivo Prem. XL. It had a frozen start up screen. The drive had started to hiccup from time to time three months back and I had ordered a replacement drive from Weaknees as a precaution. So after insuring it wasn't coming back, I pulled and replaced the old hard drive. Install and setup went very smoothly. Cable service set, network connects fine, then I get the message shown in the title and I'm at 50%. Can someone explain this note from the weaKnees instructions to me and share if this might be the issue? "Note: After installation of your new drive certain channels are not available, you will want to call your cable company and verify that the HOST ID and DATA ID that they have matches the TiVo's CableCard setting screen." Thank you. Update: FIOS confirmed everything is in sync on their end. Restarted the set-up and this time I get 75% complete msg. Tried it one more time and back to 50%. Update II: I'm a dumbass. While double checking my connections I realized I had connected the cable to the OTA antenna connection. Once corrected I was "good to go" in two mins.
