Well, it's indicating a failing drive. You may get some more use out of it, but you'll need to pull the drive and reformat it. You're likely going to lose all your recordings, at this stage. It doesn't sound like the TiVo OS can repair itself. You can get several more years and probably 500hrs capacity if you spend $75 on a new IDE hard drive and $20 on an Instant Cake CD from DVRUpgrade. Or for a little more money you can get pre-formatted drives from DVRUpgrade or 9thtee. Then all you need is a T-10 and T-15 Torx screwdriver.
