My TIVO HD (which I have had for several years) all of a sudden deleted a bunch of my saved shows. I had plenty of storage space left. There were almost 100 TIVO suggestions in addition to my shows. When I looked at it tonight, a bunch of previously saved shows were gone. I can't tell why it deleted some shows and not others. For example, it deleted some shows that I had marked "save until I delete", and didn't delete others that were not marked to be saved. It doesn't appear to have only hit shows that were recorded prior to a certain date. Has this happened to anyone else? Does it mean that my hard drive is failing? Thanks in advance for any help!
