If you can beg, borrow or steal a 2TB drive it will work when you restore the factory image with DvrBARS. As soon as it updates to the latest software you can pull it out, back it up again with DvrBARS, and restore the new backup to the 3TB drive. At that point you an follow jmbach's procedure to expand it the rest of the way.
So, what would be ideal, is for somebody to get the image updated using my trick of using 00000 zip code, Tiny TiVo as provider (during Guided Setup), run a C&DE on the updated image, pull the plug on the reboot once the C&DE operation has completed, which self-triggers a reboot (preferably before the KS [kickstart] window of opportunity, or before the "almost there" screen at the latest), make a backup of that, and upload it to you for distribution?
Helpful tips & explanations for all:
The 00000 zip code & Tiny TiVo provider trick only downloads one channel worth of empty guide data, keeping the new backup image small as can be, and saves time. A cablecard can be paired in this setup, but the channels can only be tested using "test channels using M-card" via DVR Diagnostics screens. This is just a FYI, for those who may use this trick for the many other uses I've found for it, like purging out corrupted data related to an existing zip and provider's guide data.
The reason for the C&DE with timed power-pull is to stop the drive from becoming married to the TSN of the board it is updated on, eliminating image recipients from having to repeat guided setup twice, with a C&DE between the two, to remove any existing host board TSN-to-drive marriage.
Once the software has reached a certain version number, the second screen of GS, where you select demo/home setup, has a "press enter for advanced options" option, which adds Installer Express mode to the choices, saving a big chunk of time, by only doing the absolute minimum GS needs to, leaving all the little personalized preferences to be set later through the menus.
If you want to see what software version is on a drive that boots into GS, without running it, press Info button on the very first GS screen (Select Country). It's at the bottom of the screen, when displayed.
: I had left out it is best that the only things connected, until done, are:
1. Power cord/supply.
2. Ethernet cable (or wireless, if you absolutely can't do RJ45 ethernet).
What absolutely should NOT be connected:
1. Coaxial cable for cable or antenna.
Why: If a video source is available, the TiVo will continuously process and buffer all tuners, making the resulting image larger for every zeroed-sector that is changed to in the process. A C&DE does not re-zero the sectors that get changed. Even though the buffer, per tuner, is 30 minutes, it still moves forward though more sectors for as long as the TiVo is on, and has a coax connection providing cable or antenna connectivity. For the cleanest and smallest backup image, this is a big deal.
I suppose (theoretically) somebody who insists on using MoCA, could just remove the cable/antenna input coax to the MoCA, and just use the coax for networking only.
