Acquired a lifetime oled TiVo which had a dying harddrive, since I had an identical unit I fired up winmfs, made a backup via windows 7, and applied the backup to a wd ears20 2tb and chose yes when it asked to use the other available space and supersize was put on. Booted up without wdidle but after clear all only showed 36 hrs hd recording space. I was told the 2 tb would not work in this unit so I ordered a 1.5 tb wd ears15 went about the identical process as before but had to use wdidle to get it to boot. It still says 36 hrs! What am I doing wrong???
