I have a Tivo VOX 1TB (TCD849000V) and the hard drive failed. I am trying to replace it with a WD 2.5 inch 2TB Blue hard drive (WD20SPZX) but will not boot to Guided Setup. I used MFS Reformatter to try to expand the HD size; however, I am getting an error message "This drive would have 1 media regions, which isn't supported at this time." I am not trying to save/transfer any old inform from previous hard drive. I am just trying to get a 2TB hard drive to work in this Tivo. If I need to order a different hard drive, please let me know one I can purchase or any other steps that I may have missed in order to get the WD Blue 2TB working. Any assistance is greatly appreciated. I believe that the WD Blue maybe SMR and not CMR, so I may need to return the hard drive and order a CMR HD drive. What would one recommend (max 2TB)?
