Advertisements I have a TiVo HD 160GB with WD external drive. The TiVo been in operation since 2008, the external since 2012. Have had occasional issues with booting where it sits on a few minutes more or goes into reboot loop. Kickstart drive tests show both drives good (I will also test the external on PC with WD tools as well). Also have not opened the unit yet to inspect the HD or power supply capacitors (need to find my torx drivers). Here's the thing. I was given another TiVo HD Series 3 that has never been used and still in its sealed box (another story). Looking for opinions on doing the following : -Transfer new HD to original TiVo -Transfer new power supply to original TiVo (after visual capacitor inspection) -Transfer new motherboard to original TiVo (or is this where my lifetime subscription is stored?) I don't care about the current recordings (can transfer to yet another TiVo) or having to redo guided setup. Does any of this make sense from a preventive maintenance standpoint?
