You can't move hard drives between TiVo's as the recordings are keyed to the TSN of the TiVo they were recorded on. You have to do a Clear and Delete Everything to marry a drive to a TiVo and that deletes all shows. I'm a little surprised that it actively deleted the shows (versus just not being able to play them back) but others have reported something like this with regards to new recordings which disappeared on a reboot when they did not do a Clear and Delete after imaging a new drive or installing a drive from another TiVo.Hello Tivoland. I have 2 identical TiVo Premieres with the same Hard Drive capacities, one with a bad hard drive and the other with a bad LAN port. I have swapped the hard drives leaving me with one fully functioning unit. The issue is that all the recordings from the functioning HD disappeared. I didn't get a prompt to reformat the drive or any message at all it just booted up normally and now is showing me 0% full. I have tried to put the HD back in the other TiVo but the recordings are missing there as well. Does anyone know what happened and how to retrieve the recordings?
Unfortunately, I don't think you will be able to recover the shows.
