I thought it might be helpful to separate out the users that are trying to upgrade a Tivo HD using comer's JMFS tools. The original thread is here and the tools were designed for the Premiere, but based upon the experience of several members (including myself), it appears to work fine for Tivo HD's as well. If you intend to expand only to a maximum of 1.26TB, then you're probably better off sticking with WinMFS and the instructions in this thread.
If you're a little adventurous and you want to expand and fully utilize a 1.5TB/2.0TB drive, then you can try out this recipe:
Updated 2/11/2011 (and caveat added 8/14/2011):
Thanks to some pioneering work by KenVa, if you wish to keep all of the shows on your current THD, you can possibly use a WinMFS expanded drive as a source (see teiland's posts starting here to confirm the state of your WinMFS source drive for some possible issues):

If you're a little adventurous and you want to expand and fully utilize a 1.5TB/2.0TB drive, then you can try out this recipe:
- Use an original 160GB Tivo HD Drive - if it doesn't have the latest software, install it back into your Tivo HD and force it to upgrade to the latest version (11.0j currently).
- Burn a copy of JMFS Live onto a CD (or run it from a USB drive) from the Premiere Drive Upgrade thread. Follow those directions to connect and boot up with (1) the original 160GB Tivo HD drive and (2) the new 1.5TB/2.0TB drive.
- Run the menu item to do the disk copy from your original drive to your new drive.
- Run the menu item to do the expansion of your new drive.
- If you want to verify the AAM setting, you can go to the command line in JMFS and use "hdparm -M <device>". A value of 128 indicates that the drive is set for the quietest mode.
- Depending upon the drive you're using, you may also want to use "wdidle3.exe" to check and if necessary, disable the idle timeout for your drive to prevent a "soft reboot" issue. Please refer to Section IV, #29 of the original upgrade FAQ for the full details.
- If you want to supersize the drive for the Tivo HD, then DO NOT USE the JMFS menu option to Supersize!!! This option will only work with Premiere drives. Instead, shutdown and then connect the new drive to a computer with WinMFS and use WinMFS to "turn on supersize". On a 2TB drive, the WinMFS supersize will increase your recording time from 288 hrs to 318 hrs.
- Install the new drive back into your Tivo HD and enjoy!

Thanks to some pioneering work by KenVa, if you wish to keep all of the shows on your current THD, you can possibly use a WinMFS expanded drive as a source (see teiland's posts starting here to confirm the state of your WinMFS source drive for some possible issues):
- Burn a copy of JMFS Live (at least v1.04) onto a CD (or run it from a USB drive) from the Premiere Drive Upgrade thread. Follow those directions to connect and boot up with (1) a WinMFS expanded, Tivo HD drive and (2) the new 1.5TB/2.0TB drive.
- Run the menu item to do the disk copy from your source drive to your new drive.
- Run the menu item to do the expansion of your new drive.
- If you want to verify the AAM setting, you can go to the command line in JMFS and use "hdparm -M <device>". A value of 128 indicates that the drive is set for the quietest mode.

On a 2TB drive, the WinMFS supersize will increase your recording time from 288 hrs to 318 hrs. If you already did the "turn on supersize" step with your source drive, you do not need to do it with the new drive as well - that setting will have been copied over already.
- Install the new drive back into your Tivo HD and enjoy!
Notes:
- I had been running on 750GB drives in my Tivo HD's, and since I wanted to keep some shows I tried various methods of upgrading. The failures are documented here. Given our current experience, it doesn't seem possible to upgrade from an expanded drive to a 1.5TB/2.0TB drive.
- As of 2/8/2011, KenVa successfully sourced from an already expanded drive and retiredqwest replicated that success.
- As of 8/10/2011, teiland identified an issue (and a possible workaround) if you are sourcing from a WinMFS expanded drive which shows a 16th partition labeled "Apple_Free".
Thanks:
- Props to comer for building the JMFS tools and also to retiredqwest for being the pioneering, first brave soul to try out and document success with the Tivo HD (and particularly for using WinMFS to do the supersize)!
- Thanks also to KenVa for showing us how to use an already expanded drive as a source for those that want to carry over their current recordings.
- Thanks to teiland for identifying some additional issues with WinMFS source drives.
