i was wondering too would that cause the hard drive not to work because it would see the drive as coming from another box too?
thanks and i am sorry if this is a banned subject.
Once you move the crypto chip (which contains the TiVo Service Number) from TiVo model "fill in the blank" motherboard A to TiVo model "fill in the blank" motherboard B, which I did with 2 TCD649080 motherboards, then motherboard B becomes motherboard A, for practically all intents and purposes.
When it contacts the TiVo servers that keep track of the subscription status, it reports the TSN on the crypto chip, so TiVo thinks it's still motherboard A.
Which is handy if you have a whole bunch of recordings tied to a particular TSN, or a lifetime sub tied to a particular TSN, and the motherboard goes bad.
But if you have a TiVo that does not have a lifetime sub, and you're going to buy one that does, pay for a month of sub on the old one, use the time to copy any shows on it you want to save to an NTFS-formatted partiton on a PC with the free version of TiVo Desktop, then take the lifetimed TiVo and swap in your old power supply if needed, or give it a new hard drive if needed, rather than taking both motherboards out of both chassis and having to go to the nerve-wracking trouble of Surface Mount Device unsoldering and resoldering to move the crypto chip when it's already sitting on a perfectly good motherboard.
