Lifetime is associated with the service number on the tivo board and not the hard drive.
You'll need a "TCD240" image on the harddrive, so the software knows exactly what hardware is installed. The TCD540 and TCD649 more than likely had drivers for different hardware, and why a swap of those harddrives didn't work. Here's weaKnees' offering for your model: http://www.weaknees.com/tivo-series2-tcd24004a.phpIt appears that the TCD24004A I've had for 9 years is toast - I now have the eternal gray "Welcome, Powering up..." screen after I unplugged and plugged it back in. I've tried rebooting, unplugging, disconnect network adapters, etc.
The problem is my TCD24004A has lifetime service on it that I want to keep. So I got my hands on TCD649080 and a TCD540040 from people that were no longer using them. Is there a way for me to take advantage of these other working Tivos so I can keep my lifetime service intact? I've tried swapping the hard drives with no success.
I am computer literate, but haven't been able to wade through the other threads to know if they apply to me or not.
Any help?
