    The TiVo uses 2 partitions to store the software, but only one is active at a time. When a software install occurs the TiVo installs to the unused partition and then makes it active. It does so in case something goes wrong so it can go back to the old software. If the unused partition contains sectors that are going bad, then the software installation might succeed, but have problems when reading from the drive resulting in reboots.

    The software update isn't causing the drive to fail. The drive is already failing when the software update is applied which is what is causing the problem. The same thing would happen if you installed OS X on a drive that is going bad (though OS X might have better methods of flagging bad parts of the drive or simply not allow the install).

    Appreciate the explanation. I guess that's my point... "Shouldn't the software be smart enough to use safe, usable blocks on the hard drive?"

    It sounds as if the update is being written onto bad sectors and then not being able to reboot! So it could well be that most of the hard drives themselves are NOT failing, just that part of the drives needed to be blocked off from use...

    Again, I'm no techie, but you're confirming my instincts that the TiVo updates needs to be done differently...and check for bad sectors first.

    The TiVo does have a method to check the disk (though it takes a few hours to complete and can fail completely on user upgraded TiVos) but it isn't normally run in the same way that a complete disk check isn't normally done by OS X or Windows unless the user requests it.

    I'm not sure running a 3 or 4 hour disk checking program (which basically locks the disk and prevents your from using the TiVo) every time a new software release is sent out is such a good idea. Especially since there isn't much the TiVo can do about it if the drive is going bad.

    It looks like we still have 7.3 on our S2DT -
    Is 8.1 being mainstreamed or only still for those hearty souls testing it ?

    well, got home tonight -
    and it's now running 8.1 - 12/4/06 -
    haven't noticed anything yet.... but have to see if our son catches any bugs

    Just got off the phone with Customer Service and they gave me the 'bad sector' explanation and of course since the unit is out of warranty they wanted $150 for a replacement. They had no explanation on why it worked before the update and not afterwards. No explanation on why the rest happens after 2-3 hours of normal operation. No explanation regarding the slow response. Just the 'must be the hard drive'. They also claimed that I was the first one complaining about the problem.

    If the problem doesn't go away I probably just move on to the Cox DVR. No wonder the stock is in the toilet.

    Interesting theory. However doesn't make sense since if I try to update the software again (to the good partition) I still get the same intermitent problem. Also, there has been a number of updates in the past, swapping OS partitions.

    I am not sure I am buying the "hard drive failure" theory on the new software install. Let me tell you my experience.

    I am using a Pioneer DVR-810HS.

    1. I decided to upgrade my hard drive from 80G to 320G. I bought a brand new 320G Western Digital hard drive (7200.10) At the time I had 7.3 software. Used mfsbackup -Tao - /dev/hda | mfsrestore -s 127 -r 4 -xzpi - /dev/hdc

    Everything worked great. Shows copied over had variable to 411 hours. Worked fine for 10 days until 8.1 arrived.

    2. Received 8.1 and now the machine reboots 2 seconds after getting to Central menu. Others are experiencing this too. I was not sure what the problem was at the time.

    3. Put my 80G back in with 7.3 software. It ran slow, but worked. Downloaded the service update and rebooted. 8.1 runs fine on the 80G. No rebooting.

    4. Did the same command as before outlined above copying the image from the 80G to the 320G.

    5. Placed the 320G in the machine and get the same constant rebooting action when it gets to the Central menu.

    This really blows. Did they prevent users from adding larger drives with this new software? Appreciate any advice/comments.

    How are you updating the software again? If you mean by going through the backdoor to reinstall it then it is still using that same partitions.

    Just because there was not a bad sector in a drive does not mean there will never be a bad sector. Eventually all drives will die out.

    Yes, I did try that. It was suggested by a kind sir (who since he PM'd me instead of posting, I will name only as "A Nanny Mouse") that I use the kickstart 52 code to reinstall the update. That seems to have solved the trouble after a brief bit of panic. It's presently processing the data from a forced connection. I was down to one day of programming so it's taking a little while :)

    kickstart 52 code? What's that? I suppose that question belongs in the hacks section. If an answer is permitted here, that would be helpful-- maybe someone can point me to a link. Otherwise, I'll wait until disaster strikes and then post or rummage over there.

    See the kickstart section here.

    Also, info on the help forums at tivo.com here.

    Kickstarts are things that mere mortals normally should only do when instructed to by a CSR.

    Thanks! I figured it was some obscure Merlin magic! :)

    Why would you want it to give the the "Delete?" screen? I HATE when I get that screen and wish there were a way to turn off that option. I can't remember the last time I deleted something using that method.

    Just an FYI, anytime you see the little up/down arrows at the top right/bottom right of the program information screen, this is an indication that you can use Channel Up/Down to navigate through all the selections at that level without backing out to the prior level. It works pretty much anytime there are multiple shows in that level (suggestions, wish lists, View Upcoming Episodes, etc.)

    I don't mind the delete screen, but I wish it would not go back to the beginning of the recording when I choose to keep the recording. It's annoying to have to jump to the end and go back the next time I play the recording.

    If you quit within the last five minutes and don't delete, doesn't it go back to the beginning?

    If you get the prompt it will. However, there seem to be cases where you still don't get the prompt (this was real bad in 7.x). In those cases, it starts back near the end of the program.

    This has been discussed in the DVD TiVo forum, but should be added here for completeness. DVD TiVo units by Humax and others now have an 8.1 bug where attempts to record from the front panel connectors using a composite video source and selecting composite video input from the setup screen will fail to record the audio. S-Video and Firewire recording still work correctly. I seldom use the feature, but I am sure there are others who value it more highly.
