PM sent. You can use DvrBARS to restore it, and after that you can expand it up to 2TB with jmfs. The minimum drive size for this image is 1TB. You can go up to 4TB if you restore the image to a smaller drive, put it in the TiVo and let it update to the latest software, then copy it to a new drive with MFSTools 3.2. From that point it's possible to go up to 8TB (see jmbach's 8TB Premiere thread) but it's a bit tricky. All of the tools and threads I mentioned are in the Upgrade Center forum.
