I'm sorry to learn about the problems you're experiencing with your TiVo box recently, it's certainly not the service we want for you.
I've been able to locate your account to run some tests on the set top box from our end for you, I can see that there has recently been a higher than normal return for hard drive errors, which could be linked to this issue.
Have you had this issue occur since your post? If so, I'd like to arrange for a member of the team to come and take a closer look for you. I've sent you information regarding that in a private message, which you can view by clicking the purple envelope on the top right of this page.
