Advertisements My THR 22 hard drive is failing so replacing it with the WD 2T drive is one option I'm considering. I'm struggling with just dumping the TiVo box and going over to the dark side and getting DirecTV's DVR. I've always had TiVo's since about 1996 and have a stack of used ones in the basement to prove it. The interest and support for them seems to be almost non-existent as a quick look at the forum for DirecTV TiVo on this site shows. Almost zero current posts! Anyway, my question for now is, if I replace the drive, can I use the old drive as external to view the shows recorded on it or will the DVR format this drive as I understand it will for the new internal drive? If it formats the drive and I loose the programs on it, that might make my decision easier to just cave in and get DirecTV's stuff. I just don't like their format as I've played around with it at other peoples houses that have their boxes. I learn the stuff needed for the current time or crisis with dealing with DirecTV & TiVo (InstantCake, hard drive swaps, power supplies, capacitor replacement, etc.) but then sometimes years go by without any problems. Now it seems I need to learn new stuff again. Can someone enlighten me about dual buffers with DirecTV DVR's? I think I understand that there is a workaround to make their boxes do this but I might be confused. Can a DirecTV box have dual buffers and will they be active all the time like the TiVo box? I guess except for the buffers, I will hate to give up TiVo's friendly menu's and interface if I decide to switch. I have no other option besides satellite TV and hi speed internet is not viable in my rural location. Whole-Home DVR service would not be of interest unless it was not charged at more than I pay now.
