    You might look at this. You being in Australia and all so that everything is upside down:), it may or may not be relevant but it is worth a shot.

    What's the model number of the one that had the 320 and what was the model number of the one you tried before that had the 1TB?

    Thanks for the link. Looks like that could indeed be the problem. I will transfer my recordings to one of the other TiVo's and them use the original 320GB HDD to copy and expand on the new drive.



    All of the TiVo's are the same. According to system info they are S3's. All came originally with a 320GB HDD.

    There's a number on the sticker on the back. It starts with TCD.

    Based on the location and drive size I would assume they are model TCD663320.

    If you have a PC with WinMFS on it, hook up the 1TB, then click on mfsinfo for that drive and copy and paste the partition map info part here.

    Yes you are correct. All 3 are this model.

    Based on the above partition info I will copy off the original 320gb hdd and it should be ok and not add the extra partition.

    Thanks for all your help. I really appreciate it.

    Since you're going to transfer off the shows from the 1TB, you don't need to keep it unmolested, so use it as a middleman if what you have is the Australian version of the S3 HD.

    Use WinMFS to copy the 320 to the 1TB, put 1000 in the box where you specify the swap partition size (that's only about 15 minutes of best quality analog video, cheap insurance), and then when it finishes and asks if you want to expand to use the rest of the 1TB, say yes.

    When that's done, click on mfsinfo, check out the partition map, make sure you have no more than 15 partitions and that none of them are "Apple Free" partitions. (if there's a little space left at the end of the drive, the way the MFS Live cd tends to do, it'll make that an Apple Free partition, and we want to avoid that)

    If you've got 15 (3 MFS sets, plus partitons 1-9), and nothing else, you're good to go.

    Put it in the TiVo, make sure it boots, if the original 320 wasn't already set up the way you needed, do it now, then when that's all over, take it back out, hook it and the 2TB to a PC, boot with the jmfs cd v1.04, and let it copy the 1 to the 2 and expand the way it does by adding a single MFS Media partition, which will be the 16th and last allowable on a single drive partition.

    That's the way I finally did it on my S3 HD, and it's been working fine since.

    Yes, do as Unitron instructs.

    320GB ---> intermediate 1TB drive via winMFS with swap carefully adjusted to avoid creating an extraneous AppleFree partition. Let winMFS expand to fill the 1TB drive.

    You should end up with a 1TB that uses its entire capacity but does not have an AppleFree partition. If you do see an AppleFree partition on the 1TB, redo the 320GB ---> 1TB via winMFS but adjust the swap size to "use up" what would become the extraneous AppleFree partition.

    Take the 1TB drive and copy / expand via JMFS to the 2 TB drive.


    Unitron's 2 step process ensures that you keep all the created partitions below the 1TB limit in the TiVo disk drivers. This differs from the process in the first post of this thread which goes from 320 straight to 2GB. That creates a whopping 1.7 TB partition that may initially appear to work, but likely will become unstable once the system writes beyond 1TB in the big partition. Crashes, reboots, or possibly just overwriting of older shows despite them appearing to remain in My Shows listing.

    Unitron's 2 step method might save a lot of grief. I think it is worth doing it his way unless you somehow have specific knowledge that TiVo has rewritten its disk drivers to properly address partitions greater than 1TB. Nobody on the web seems to be reporting such an updated was made by TiVo.

    Thank you for the vote of confidence, but just for the record the big swap size is to get a big swap size.

    (don't know for sure if it's necessary, but better to have it and not need it than the other way around. Like I say, cheap insurance)

    I think that, unlike MFS Live, WinMFS will make sure not to leave any extra space when expanding, and it will do so even if you don't specify a swap size different from the one on the source drive.

    I tried MFS Live with swap sizes in a number of different sizes slightly above or slightly below 1,000 MB and it stubbornly insisted on leaving a little-bitty Apple Free partion no matter what.

    Thanks for clarifying that point.

    BTW, my S3 --> 2TB via your method has now successfully filled its entire capacity AND the oldest recordings do not appear to be corrupted by the newest ones. That suggests the file system is happy.

    I don't understand why we are not hearing reports of problems after more than 1TB is written on the non-XL Premieres. Those who went direct from 320GB to 2TB ended up with a 1.7 TB partition via JMFS.

    It just takes a long time to actually fill a 2TB drive with recordings and then go back and verify the oldest ones are actually intact.

    Ok well when I get time after all these shows transfer (will take days) then I will do the process.

    This partition map was from the straight copy from a 320GB>>2TB and since it only has 14 partitions would it be ok?

    If I have to do the process you outlined above with all 3 TiVo's then I will have to use the same 1TB HDD as the intermediary drive in the sequence which isn't a drama.

    Thanks

    There's a thread in the S3 forum on using jmfs on the S3 HD (and S3 HD XL), and since you've got Series 3 platform machines and not Series 4, you should probably be over there seeing if anyone has reported long term success with a partition larger than 1TB (or 1.2TB, depending on how you measure).

    I made sure to fill up the drive during my first week, taping shows all day long, until I was convinced that there was no issue with any of my existing shows and that the deletes fell off properly. I've been running with 2TB drives in my Tivo HD's since 12/2010.

    Interesting.... maybe TiVo silently updated their disk software drivers to handle the big partitions. Not a bad thing if they did.

    Tivoitis,
    I am recording all the time on the first one I did to see how it goes. I will be nearly full within 24hrs as I transferred over many movies to it so I will see how it goes too and let you all know the outcome.

    Unitron,

    Ok I did the TiVo your way yesterday so I will see how it goes.
    The first TiVo I did was straight from 320GB>>2TB and I have filled it up with recordings and it's going great also.

    If I have any issues with either way I will report them here for you guys.

    Though a fairly old post, I think this maybe needs to be reiterated from time to time. For TIVO drive upgrades your best drive will be one rated for AV (video) usage. True that any drive will work, but the advantage of one designed for A/V is it will continue writing in spite of any errors encountered. I'd much rather have a momentary blip than a huge 30~45 second gap while a non-AV drive tries to perform error recovery.

    Just my 2ยข worth.
