    Found the info on the scripts. I'll attempt when I go through the info and have time. Thanks again!

    Tivo is locked in a reboot cycle again and lost scheduling last time I had it running. Did a boot on the 1TB that had been working to test it again because of the scheduling issue. Thought it might bring it back up. I'm putting this Tivo aside for a while. 3 days of messing with it are enough for now.

    Which drive is it doing the reboot cycle on?

    The new 1TB that I rplaced the failing one with. I saw the scheduling had not updated, even though the download said it was successful.

    Might want to try another image on the drive. Also how OS the TiVo connecting to the service. Wired, wireless, POTS.

    Also sometimes you will need to force a connection several times. The other thing I have seen is that you need to delete the scheduling first and then force connect several times.

    Tried both wireless and wired directly to router. Have done multiple images over the past week and many reboots. With the different issues, I will probably replace the caps to be sure it's not that but April is hectic with work and otfamily issues so will probably be May when I am on vacation before I do more work on this one. Thanks for the ideas!

    Well, since murrayamorris is busy, I'll throw my hat into the ring.

    I have a 652160 (2 of them, actually) upgraded from 160G to 1TB using WinMFS several years ago. On of them has started showing indications that the drive is going to leave this world soon, so I replaced it with a 2TB drive and migrated everything over using the current version of WinMFS. It expanded the size of my existing 14/15 pair to the end of the drive, and everything seems to be working okay. I'm showing 318 hours of HD now.

    So now that's got me thinking...could I start from a 1TB 658000 base image and expand to 3TB (adding a new 14/15) that way? (If so, can someone point me in the direction of a 658000 image? Or a method for constructing a similar partition layout?)

    If I did the same thing I did with a 2TB drive, but used a 4TB drive instead, would WinMFS expand 14/15 to the end of the drive or would the partitions be limited to 2TB?

    Also, since I still have an empty partition 16, can I use JMFS to add yet another partition beyond? (I think I could fill a single 4TB drive that way.)

    Do we know what the upper limit on total addressable size on TiVo HD's with current software is? (I have v11.0m now.)

    I'm willing to get a 3TB (or 4TB) drive and experiment some, but I don't want to re-cover ground of what's already known about the 65xxxx's (nor waste time trying something that everyone but me knows is impossible).

    Thanks in advance.

    Here is what I know. I have an OLED S3. I placed my 2TB image on a 3TB drive and it booted and ran fine. Problem going any further with an OLED S3 is that it has only a 32bit MFS which can only address 2TB. The HD series S3 have a 64bit MFS which can address a much larger size.
    It stands to reason that it is very likely that we might be able to create a single 3TB drive for the HD series.
    WinMFS does not like drives over 2TB in my testing. So you would take a 1TB HD XL image copy it to a 3TB drive. Boot the drive in the TiVo to make sure it works. Then use JMFS to expand it to 3TB. Put it back in the TiVo make sure it works and then record everything you can to fill the drive up and make sure it holds all 3TB of recordings without failing.
    If you are using a 1TB image that was expanded from a smaller image, you will have to copy the image to a 3TB drive, then coalesce partitions 14 and 15 into 14, boot the drive in the TiVo to divorce partition 15. Then use JMFS to expand the drive to 3TB. Put in the TiVo and record everything you can to fill up the space to make sure all 3TB is accessible.

    I can hook you up with a 658 image that I got from somebody back in December of 2011, but I don't know when they actually made it, so I don't know what version it is other than that it's older than 11.0m

    But even sticking it on a non-expanded 1TB drive, I wouldn't have any faith that it would work out in the long run on a 652. It'll boot, but the first time it "phones home" and reports a 652 TSN and some version of the 658 software who knows what confusion may result.

    I probably shouldn't tempt you into likely disaster, so on your head be it.

    https://dl.dropboxusercontent.com/u/49887720/658000.tbk

    If it were me, I'd use WinMFS to copy a 652 image to a 2TB and then expand into the extra space as a separate step, and then use jmfs to copy it to a 3TB and add a 16th partition, and try that and forget about a 4TB for now, although I have no way of knowing if the 3TB would function properly.

    I think the use of a 658 image (massaged with lots of voodoo) on a 652 drive was done prior to 11.0h when the TiVo couldn't handle a partition bigger than 1.2TB, which now it can.

    Well, here's some follow-up:

    Evidently, my issues with crashing were not (or at least not entirely) due to a failing HD. I was continuing to get crashes and reboots on the 2TB drive. :(

    (And AAMOF, the 2TB drive was a modern WD "Green" drive, and I DID have to use WDIDLE3 to kill the auto-parking. Before I did that, it was exhibiting the telltale problems with failed soft-reboots, where hard-reboots worked fine. WDIDLE3 fixed that.)

    Also, as a test, I swapped the power supplies of my two TiVo HD's, and the problem did NOT migrate to the other unit along with the PS, so it's not that either.

    But along the way, I did learn a few interesting things.

    I made an image onto a Seagate 4TB video drive with WinMFS, and it's running on that right now. Fewer crashes now, but not none.

    SO . . . a TiVo HD will boot and run off of a 4TB drive. Since it worked with a 3TB, I expected this, but until you try it, you never really know for sure.

    One of my first tests was letting WinMFS make as large a partition as it could, which turned out to be precisely 2TiB. This gave me an image that was essentially 2TiB + 160GB--a tiny bit OVER 2TiB.

    The TiVo HD would boot, go to green repair screen, run for a few minutes, then reboot, and repeat that cycle over and over.

    SO . . . I don't think a TiVo HD on current software can address more than 2TiB of total space. :(

    I have not yet tried attaching an external drive to exceed 2TiB of space, but I have my doubts that it will work. (Not to mention that any test I do means many hours of down-time to make a backup!)

    If anyone has any expert opinions on whether I should be more optimistic or pessimistic about external drives, let me know. If it DOES work, then the procedure for combining them back into a single large drive might be an option as well.)

    Thoughts?

    Try the test again using JMFS to expand the drive. I am not sure if WinMFS properly modifies the MFS structure for over 2TB storage. I know JMFS does as I have taken the Premiere to 4TB. If it does the same using JMFS to expand, then I would agree that taking the TiVo HD line over 2TB is unlikely.

    So . . . in the end I gave up.

    I still think that over 2TiB on a TiVo HD is not going to work, and some other research I've done in the mean time seems to support that.

    But the real reason I gave up was that my problems with spontaneous reboots were with the system board (not the drive, nor my power supply), and it just was NOT acceptable in the long run to have a TiVo that would randomly reboot 3-4 times per day--often in the middle of an important recording.

    I now have a Roamio Plus, and migrated the 4TB drive to it, with MANY MANY thanks to telemark.

    And . . . MANY MANY thanks to everyone on this thread, particularly jmbach and unitron for their technical advice; to CrashHD for getting the conversation started; and to murryamorris for leading the way at actually trying it out.

    How did you establish that the HDs had good power supplies?

    I have two TiVo HD's (purchased at the same time, even), and I pulled both power supplies and swapped them.
    The symptoms that I'd been seeing on my "bad" unit stayed on that same unit, and didn't migrate over to the other along with the power supply. The "good" one continued to hum along reliably since then on the swapped-in power supply for a couple of months now...and still is.

    Be prepared to get told that's not enough of a test. I'll let unitron have at you on that. He has links to pictures of what should be visually inspected. It is true that it's a good time to think about replacing the PS filtering capacitors, even if they appear fine with visual inspection. It's an ounce of prevention...pound of cure scenario, but still your decision to make.

    If you swapped power supplies and the symptoms didn't follow, then likely something else is to blame for those symptoms.


    It wouldn't hurt to check those power supplies with a voltmeter, and perhaps tweak the adjustable resistor if the readings are just a hair low, but if that's enough to cause problems it could be something on the motherboard is going bad and that would explain a greater than usual intolerance for less than perfect power.


    (It still wouldn't be a bad idea to replace "the usual suspects" capacitor-wise, as preventative maintenance sometime when the TiVo is going to be opened up anyway.)
