Advertisements The hard drive died in dad's Tivo series 4 premier over the weekend (750500). I took the old hard drive out, grabbed a 2TB WD red drive, found a 750500 image and flashed it to the WD red drive using DvrBAR. I've tried to research whether DvrBAR will expand the image to fill the drive, and I don't think it does. Then again, I don't know if the size on the drive depends on the image I downloaded. Will I need to expand the new hard drive to get the full size, and if so what software tool do I use for that?
