Advertisements TiVo Premiere TCD758250, which I replaced my failed 2TB drive with a 6TB WD Red Plus (so CMR) ~3 months ago. Image was TCD758250-20.7.4B.RC3-4TB, and I did the expand as per usual procedure. Current software version says 20.7.4d.RC15-758-2-758. Earlier today all was normal, but after recording and watching a ~3hr game, I want back to my shows and all shows are gone. Recently deleted recordings is empty. In history, the shows that were previously there now say "Not Recorded / Unknown Problem / Info: The show was not recorded because of an unknown reason (R115)". Recording capacity currently says up to 961 HD hours, and free disk space up to 957 HD hours. This is the second time this has happened, but the first time I was away and didn't catch the details. It did for a while not want to record new recordings as if there wasn't space for them. I thought maybe it was a bug/feature with the software upgrade, but haven't found similar issues posted. Ideas?
