I recently took my 1TB TiVo HD drive and transferred it into my TiVo Premiere with no problems (used a modified version of MSFlive). The reason I think this went so smoothly is I just copied the original 320GB Premiere drive onto the 1TB drive and used MSFlive to expand the image. Problem is, now I need to recreate the TiVo HD drive and I don't have the original drive to port over the image. I do have a .tbk image file, but I think it's corrupt or something. The TiVo boots and everything, it just sporadically displays a message saying "A hardware problem has been detected". Also for some reason it doesnt display the TSN under system information. Does anyone know how I can get a clean image for the TiVo HD? I even tried using a copy of InstantCake, but it doesn't like the Optical Drive in my Macbook Pro for some reason. Any help or suggestions would be much appreciated.
