TiVo HD XL question - upgraded to 2 TB internal, but want 1 TB external to work too..

Hi, Sorry if this is a repeat question, while I searched here, I got old or conflicting information and was not able to glean the correct answer.



I've got a TiVo HD XL, it was set up with 1tb internal and 1tb external. The internal died, so I got a new 2tb drive and put it internal. I used MFSLive and an image for that drive. I got that all up and running and put the 1tb external on. It asked me to pair, I said yes, but it never did.



Searching here I found the following, but don't know if it's true:

- 2.2tb is the max

- internal drive cannot be larger than external



But also saw people saying:

- they have 4tb storage

- use MFSLive/WinMFS to marry B to A



I tried both MFSLive and WinMFS, MFSLive didn't seem to do anything even though the command came back successful, WinMFS did seem to work, but kept causing reboot loops at "Almost There...". When I disconnected the external drive, TiVo recognized that and asked to divorce it. So this seemed to almost work...



Searching more, I see JMFS Live, but didn't see the exact situation I have and I'm leery to try it without asking first.



Will JMFS Live do this? If not, any other options?



Thanks!

Ron
