Advertisements Update on my freezing, stuttering TiVo. I just got a message from Weaknees. They tested both my hard drives and the diagnostics didn't show anything. They did say that in some cases the testing doesn't pick up a bad hard drive. They are going to replace my Weaknees hard drive, and the original hard drive, so we'll see if I still have these issues. Not having my TiVo (for almost a week, now) is driving me nuts!!!!! I want my TiVo back!
