I recently upgraded the internal drive on my S3 using the Bumwine instructions. It was easy, and successful. Now I want to use the same method to upgrade my TiVo HD. Does anyone know if I can use the Bumwine instructions to upgrade the TiVo HD internal drive?? I couldn't find any post that specifically said this method works on the TiVo HD. I would like to use these instructions because I'm familiar with them from the S3 upgrade. Thanks!
