    hehe - ok, thanks. he too has said it seems like a toaster.... damn Tivo - with most drives, you get a few days warning as the thing starts making weird noises. With Tivo - it just plain dies. I imagine there's a good chance the actual drive may still be usable, and that there was a software glitch that trashed the boot file.

    Get the manufacturers drive diagnostic and run it. If the TiVo drive passes SMART but has some bad sectors, it might be reassigning sectors (read erase) to make it the drive still usable. replace it, don't Recertify it.

    I took a fast look at that after a search, but that doesn't appear to be Windows (or me) friendly. :(

    I've had that happen A LOT over the years with both Premieres and HD models. I run WinDLG, from WD, which usually says there's nothing wrong, then I re-image, after losing everything by using both the read tests and write zeroes with WinDLG, and the unit will run like new until it happens again. I then used HDDscan, a 3rd party utility that measures the read times, which shows that the most frequently re-written areas of the drives have very long read rates, at which point it seems silly to re-use the drives. It takes 2-3 years for the most drives to end up this way. The annoying part is that WD's utilities pass the drive, and SMART diags, but frequently, if I repeatedly run the TiVo SMART tests, I'll get a "Fail 7" and a reference to it being read related. I think WD has some pretty loose standards, in order to prevent their utilities from failing a drive, and just how bad the drive performance has to degrade before the SMART values drift out of their thresholds, which they set. It would be nice if SMART attributes were more standardized, as opposed to what the manufacturer decides is acceptable... The acceptable values on AV drives are a little tighter, but not enough IMHO...

    It seems that the last few updates TiVo sent out has reduced the frequency of my units going into the GSOD reboot loop. But, it could also be that I manually reboot my TiVos frequently, as well as clearing the guide data every three months. While it requires a few hours to rebuild, I don't lose my recordings, season passes, or thumb ratings. I only lose any manual recordings that are in the To Do list. I think, over time, the logs of what didn't record, and why, due to things like cancelling SPs, or re-organizing my SPs, get too large. TiVo is a bit over-zealous when it comes to making sure that six months after you cancel a SP, it still logs every episode not recorded, and every episode deleted. I think it may cause the logs to get too big, and that's why it can't repair itself. Manual reboots, and clearing the guide data, seems to help. I was using a raw disk editor to look at the logs on GSOD reboot looping TiVo drives, and it keep saying that there were too many inode entries in a table, (like saying there were 1,051,654, and the limit was 200,000, only to reboot to attempt repair, and log the same issue at every attempt. I don't know enough about the file system to offer more, and the drive in my computer, where I was saving all my research suffered a sudden mechanical failure/death. I spent nearly a year working on documenting these errors is detail, only to lose it all. :(

    I've also taken drives that passed WD's tests, used dd_rescue to put an image on from a brand new, tested, drive, then used dd_rescue to copy from the drive I just copied to, and logged read/retry errors. I've tried it on multiple different computers, none of them Gigabyte (to avoid a possible HPA issue), and it all winds up the same. I'm at a loss for what more I can do. It's very rare for any of my TiVos to last a year without getting caught in a GSOD loop, until now, doing what I have been doing, which also includes not using the TiVos for anything except the DVR functions. No Netflix, no Hulu, just DVR use only. If TiVo hadn't sued anybody else out of contention for a competitive DVR, I'd have probably gave up years ago.

    I guess I have been lucky as I have yet to date experience any of the issues you mentioned and I don't do anything special for prevention. I just let my TiVos (648 and 748) be Tivos and let them do what they do best.

    Hmmm - this may or may not be the best place to post this basic questions. I have a Premiere XL with a 1 TB drive, over 3 years old and off warranty, with PLS. I want to expand the internal hard drive to 2 TB. I'd rather keep my recorded programs, ST's, and the like, but it's only television, and most of the non-copy-protected shows are backed-up to a readynas fileserver (though I lose the captions).

    I have a new windows PC, with oodles of USB-3 and esata ports, oodles of free disk space, as well as an assortment of adapters I can use to connect a couple of drives. I am respectful but not scared of command lines.

    Am I better off simply making a jmfs boot CD and using it to copy and then expand the Tivo drive, or should I use DvrBARS to copy, and then jmfs to expand?

    And thanks to comer and ggieseki and all the others who have contributed to making such options available to the public including yours truly.

    It's about 6 of one and half a dozen of the other as far as basic copy and expansion goes. If you don't have too many shows DvrBARS in the Modified Full mode may do the copy faster since it only reads and writes what it needs to instead of the entire drive. On the down side you'll still have to boot up jmfs to do the expansion.

    Either way, as long as you're going pull the drive out of the TiVo I'd keep a truncated backup around for the future.

    I have a TiVo HD. It's a two drive system using WinMFS. I backed up both drives using DvrBARS. I'm restoring A Drive 1TB to a clean 2TB drive. How do I restore the .5 TB B Drive to the 2TB Drive?

    You can't do a 2-1 drive upgrade with DvrBARS at this point. I haven't written any of the code to resize or relocate partitions yet.

    Since it's a Series 3 you can do it with MFS Live. Not sure about WinMFS.

    How do I perform a 2-1 drive upgrade with DvrBars? I only see the option to Restore one of my Backups or the other. I have a 1 TB VHD and a .5TB VHD. WinMFS says the function isn't implemented yet.

    I have not tried anything like that yet. What I would consider doing which you may have already done is to restore your backups to the larger drive with DvrBARS and then use WinMFS to expand. Not sure if it will work. What I think has the highest probably of success is to divorce the external drive losing only some of your programs then expanding the single drive with WinMFS followed by adding the external drive with WinMFS. Not sure about a 2 drive to 1 drive conversion.

    Unfortunately restoring my drives with DvrBARS didn't work. WinMFS doesn't support 2 to 1 because my Drive was expanded with WinMFS. I'm unable to divorce the external drive because it was expanded with WinMFS. I have both VHD's mounted in Read Only Mode and a clean 2TB destination drive. I can do some testing if you like. I've uploaded the Mfsinfo.txt file.

    The only thing I can come up with to combine 2 drives into one drive is not very eloquent and may not capture all of your programs. Essentially identify what recordings are located on your external drive and using Tivo desktop, pytivo, or the like and transfer those recordings to your computer (or even another tivo). Then divorce the extra drive. Copy the single drive to the larger drive then expand ad supersize. Install the drive and copy the recordings back. If the copy bit is not set you can transfer the recordings. The difficult part is identifying the recordings on the external drive. Ggieseke might be able to help with that. Not sure. But that is the best I can come up with at this time. I'll keep on thinking on it. Like to see something more eloquent.

    Since it was expanded with WinMFS and drive A already has 15 partitions I can't think of any way to coalesce them into 1 drive at this time. If the total number of existing partitions for both drives was 16 or less it probably wouldn't take too much work to copy the Drive B partitions and modify a few places in the header, but that's not an option in this case.

    Even if you divorce the external and use jmfs I don't think it could expand the main drive into the empty space with that partition table. If you can transfer all of your recordings to a computer I do have a 2TB 652 image that would make starting over from scratch much quicker.

    I can say that WinMFS will take an already expanded S3 drive and expand it again by just increasing the size of the 15th partition. It has been about 9 months ago when I did my 648 this way. I took it from 1TB to 2TB.

    I think JMFS would add the 16th partition in this case, however, I am not sure if the 652 would acknowledge it. It might. When I looked at videobruce's working 652 2TB image, it had 16 partitions, 2 WinMFS like and one JMFS like. Not sure what program(s) was used to do the expansion.

    Using the menu in JMFS it only detects the 1TB drive.

    Can you use JMFS to copy the 1TB drive to the 2TB drive then expand. You would have to supersize with WinMFS.

    I need it to recognize my 500GB external drive and my 1TB internal drive. I'm trying to do a 2-1 drive upgrade.

    I have a 746 that I want to blow away with a new image.

    After an expander divorce, I'm getting a looping GSOD. Tivo support of course can't help and want stupid amounts of money just to reimage my drive. I don't care about any of the data on the drive, I just want to start from scratch.

    Do you have a 746 image I can get access to so I can blow away everything on the drive and start from scratch with your tooling? The original drive is still fully operational, just a bit corrupted.

    Please shoot me a PM if you get a chance...
