Yesterday my Roamio Pro stopped recording the programs I had scheduled at that time. I noticed the red light go off and I started the recording again. It recorded a few minutes then it stopped again. I restarted the box and experienced the same symptom. I then ran through the Network Communication as I had received a message on one of my Mini's yesterday morning that that Tivo had a communication issue but they were working on the issue. This made it sound like they were having a server problem on their end. That message did go away later. The manually initiated connection to Tivo was successful and I started the recording again. It ran for an hour or so then quit again. If I go to recording history it does not tell me why the recording stopped. Tivo Support suggested I go to defaults then reset the programs and todo list menu option. Then complete communication again to re-download the guide etc.. I did that and I my to-do list repopulated recordings for this evening. I will find out tonight if my scheduled recordings complete as shown in the to-do list. My thought though is possibly the hard drive is going bad. It's at 59% usage and my theory is once it hits a certain spot on the drive it quits recording. Tivo support did mention if this did not fix it they would send me a replacement Roamio Pro and said they would tell me how to transfer the recordings but the passes I believe would have to setup again and obviously a lot of programs are seasonal, setup with my network and other tivo devices might be an issue if the device itself is replaced. I have had a bolt replaced over a year ago and the replaced unit still shows up on the tivo APP and minis even though it doesn't exist. Has anyone ever experienced this scenario before? Is Tivo support's suggestion a possible solution? Ideally if I have to replace the hard drive, I would like to clone it as I have over 120 Passes and obviously a lot of recordings and not replace the Tivo.
