    I kinda assumed it did some checksum validation on the download when it was completed, but maybe that is assuming too much... You would think that would be a requirement.

    Agreed, seems like a basic requirement...but you never know. I'm also wondering how unconditioned power; power surges/spikes, brownouts or other fluctuations during the download might affect the data while writing to disk.

    It's definitely a requirement.

    Outside...
    The download becoming corrupted during transmission is possible, but even the weakest TiVo units certainly should be able to do some basic checksum hashing on the bits as they come in, and verify the writes to disk before continuing to the installation; and should reject and re-request any bad data when it's detected.

    /darn you Jerry, making my post redundantly redundant ;)

    Oh sure...inject your "inside knowledge" and wizardry into the conversation while we're trying to defend TiVo. Now the flood gates will open with questions about what's causing these issues and what's being done to resolve them. But then you knew that would happen...didn't you? ;) Hope you can answer them better than I or some of the rest of us down here in steerage. :D

    Virtually any hard drive built with an IDE or SATA interface in the last 7 years, i.e. most any drive installed in a TiVo, has built-in mechanisms for error detection, correction, and remapping a sector when a bad sector is detected. There is at least one track on the hard drive reserved for relocating bad sectors. It doesn't matter what operating system is running, this happens at the hardware level. Once bad sectors are seen by the OS, be it Windows, Mac OS, Linux, etc., the drive is on its way to dying.

    If a TiVo is having software update problems due to bad sectors, then the TiVo's disk volume is already near its end. The problem would usually show up as pixelation/stutters during playback before the software update. If you want to learn more about how such intelligence/monitoring/autocorrection goes on in modern hard disks, do a web search for 'S.M.A.R.T. hard disk remap' or similar.

    The idea that most TiVo upgrade problems are related to physical hard disk failures, at least problems that cause specific functions to work improperly/poorly rather than making the TiVo stop working completely, is pretty silly.

    So you are saying its ok to put out buggy software and not fix it for half a year because doing otherwise wouldn't fit their schedule?

    A new problem on my end. Now Tivo 1 (DT) and Tivo 2 (540) can not see the Tivo 3 (240). Did a reboot and it came back but now its gone again. Never had the problem with the 240, usually its just the DT and 540 that lose contact. Guess I will have to reboot everything again this morning. If this keeps happening MRV is going to be useless to me. Hope the fix is coming soon.

    Going to change the network settings, but backing out before making any changes, temporally fixes the problem for about 10-15 mins. Transferring is fine once started.

    better than rebooting

    Thank you so much. This worked! And it is better than rebooting.

    A new problem on my end! My Tivo (540) is ignoring Season Passes. The episodes it missed aren't even in Recording History, although they're in the Program Guide when I scroll back a few hours. We have a local station here in Chicago that specializes in classic programming; every Sunday morning it runs three "Little Rascals" shorts, 20 minutes apart, between 6 and 7 AM. My S2 recorded the first one but blew off the other two. When I go into the episode descriptions for next week, it claims it will record each of the three, but I'd be an idiot to trust this steaming pile of crap these days. FWIW, there were no conflicts. The Tivo just failed.

    what does it say in the recording history for this morning?

    Is each 20 minute short treated as it's own distinct episode in the program guide, or is it more like the Little Rascals hour type of thing?

    Each is treated as a distinct episode. The Tivo recorded the first of the three and blew off the other two.

    Little problem I've been getting on my S2 DT since 9.1 is video / sound glitches... but ONLY when flipping through the guide with everything still playing in the background. Other than that I've yet to find any "issues" with my unit. Would be ncie to know when a STABLE 9.2 will be coming out.

    Edit : My software version is stated as 9.1a-01-2-649

    Do you have any season passes setup to keep until you delete? If so, this is a common user error that prevents the TiVo from recording new episodes because there is no room.

    Well, I do, but that wasn't the issue; I've had Tivos since April 2000, so I'm not a noob. The "Recently Deleted" folder had eight or nine hours' worth of programs in it at the time, far more than needed for two 20-minute shows. And even if that were the case, I'd expect the Recording History list to have entries for those two episodes explaining why they couldn't be recorded. (For that matter, I'd like to think there's some kind of mechanism to tell the user "This Tivo will record no further programs because the drive is full. Please delete some programs if you want to see anything new" or something like that.)

    Similarly, to forestall this question, no, I don't have the SP set to "Keep only 1 episode." But even if I did, I'd expect the Tivo to have recorded all three, keeping only the last, with entries in the Recording History explaining its action.

    Anyway, to prevent another occurrence, I've set up a manual recording that puts the entire hour into a single recording. But this shows me another bug: In the Recording Options screen, I've set the Start Recording time to 1 minute early and kept Stop Recording at On-time. But then the Repeating Recording screen tells me "Every Sun at 6:01 am" -- one minute late -- with Duration: 1 hour, not 1:01. I have no idea how to fix this.
