    I got through 9 pages without seeing this...

    I saw the drive limit was +2g. Does this mean that if a standard Premiere 4 with 75 hd hrs using a 500gb drive then I could use this tool and upgrade with a 2.5b drive and get 396 hours (317 *1.25)?

    If I chose a 3gb drive would it use the size of the 2g + .5g = 2.5g then ignore the remaining 0.5g?

    Thanks

    edit - never mind, further reading points out that any total greater than 2tb results in a negative space bug which I assume is a display only issue.

    In theory the XL4 with its 2TB can add a 2TB external drive although at this point it can add only a 1TB drive since that is all that WD and TiVo conspire to have available on the market.

    You can see if a Premiere 4 can be expanded with JMFS then add an extender drive. If I recall, there was another thread on TCF that tried this and did not work. I'll see if I can find a reference again and post it.

    You cannot use a 3TB drive at this time as the APM that describes the partition structure does not support drives over 2TB.

    Just did the upgrade on a fresh non-initialized Prem 4 to a WD20EURS.

    I used the app noted in the FAQ to check the AAM acoustic settings and it seemed to be acoustic_management=enabled from the factory. I think that makes sense since that disk was labeled as a DVR drive.

    I couldn't run the WD app to tell if intelli-park was enabled because it seemed to not like my OS. I couldn't tell for sure but proceeded anyway. I did a few soft-boots and it never hung so I am assuming intelli-park was disabled.

    Upgrade went very smooth and the never-powered up original 500g drive is in the static bag as a backup.

    Thanks for the instructions and app.

    Hi guys, is it possible to copy/extract just specific files from the original tivo Hard Disk to an empty hard disk using jmfs Live CD ?

    I wish just to back up specific recorded shows.
    Thank you

    No.. AFAIK, if one *pre-hacked* a Tivo, THEN one could, using special tools, extract recordings.. But that talk also isn't allowed on this forum.

    but why I was able instead to backup the full hard disk to the 2 tb hard disk to increase the tivo capacity ?

    Because that "just" copies the entire drive and does a few very specific things like changing partition sizes.

    As a fairly stupid analogy, think of it you copying text from a language you can't speak to a bigger piece of paper. You can look at the original and copy it directly, but don't understand what it means.

    So basically, AFAIK, people have figured out the basic partition sizing info, but the various show info is encrypted to specific hardware, so even if you knew the specific show info you couldn't just copy it "out" of the hard drive... on an unhacked tivo.

    Again, you could just download the shows *from the Tivo directly* with kmttg or other tools... assuming they're not copy protected.

    thank you

    Each TiVo does it own encryption so a hard drive from one TiVo will only work on another TiVo of the same model if you do a C&D all, then you have no programs left to watch. Xfer programs to a PC is the only way that this forum can tell you how to save a program. When I get a new TiVo to replace one I have, I just xfer all the programs to the new TiVo, than sell the older TiVo.

    A week ago I upgraded one of my THD's from a failing 750GB Seagate DB35.3 drive (had replaced the original drive when first purchase in Jan '08) to a WD20EURS drive using JMFS for the copy and then WinMFS to check the partitions and expand the last one (SuperSize had already copied over from the source drive).

    Here's the partition table of the source drive as reported by WinMFS:

    As you can see, the 4K alignment gets offset for good after the single 512 byte partition 5. It looks like shifting partition 6 by just 3584 bytes, would've brought all the remaining partitions into alignment. (I don't know if that's true or possible - that's just what I think I'm seeing)

    For what most users would consider 'normal use', the upgrade 'seemed' to work perfectly. But the way I use a TiVo is far from normal. I record or buffer-watch TONS of sports in as little time as possible, trying to catch the 'best' parts. Even if I only have 20 minutes, it's not unusual for me to "watch" a couple football games - FF'ing through to catch the 'best' parts.

    Clearly, this type of use puts much more demand on the hard drive and the interface to it than typical. As you might imagine, I noticed a significant dropoff in performance between the DB35.3 (7200 RPM, 512 byte sectors with aligned partitions) and the WD20EURS (IntelliPower (max about 5200 RPM), 4k sectors, with unaligned partitions). Also, when I was FF'ing through the 9 hours of ESPNHD coverage of Wimbledon yesterday, it was very sluggish, hesitated several times, and froze and the TiVoHD rebooted itself twice. I've not experienced that with other drives (512 byte).

    I haven't figured out a way around this yet, but I do have a Premiere (2-tuner) in the bedroom and a THD with a WD10EVDS (512 byte sectors) drive in the living room that both perform very well. I may be able to exchanges places with one of them, but I could really benefit from the larger capacity of a 2TB drive.

    Since it looks like my opportunity to get a 1+TB 512 byte HDD has passed, is there anything I can do with the WD20EURS (or any other advanced format drive, like the Seagate SV35 series drive) to at least get the media partitions to start on 4K boundaries?

    To help get me back up to speed on understanding the issue with AF drives, I just finished re-reading Seagate's Transition to Advanced Format 4K Sector Hard Drives and Novell's Partition alignment of drives with internal sector size larger than 512 bytes.

    The Novell knowledgebase paper says that any partition alignment must be done before creating a filesystem on it, so I'm wondering if anyone has tried doing this or if they think it's possible to do on a TiVo drive with any common utilities.

    Any advice or suggestions?

    Thanks!

    Thanks for the jmfs utilities, I just successfully upgraded a friend's Tivo!

    One question: I use Linux (Debian) as my desktop OS, is it possible to copy the utilities from the /root directory of the ISO and run them directly? Or, better yet, is there a .deb package?

    So close,...
    There isn't a .deb package that I know of but you can copy the tools to a folder then add it to your PATH. Be sure to add bootpage and tivopart.

    The source code is available so you probably can compile it yourself.

    Comer, thank you so much for creating the jmfs Live CD. I converted a 1 TB Premiere XL to 2 TB and I'm amazed how easy it was. Copying my old drive took about 8 hours, but the rest was very quick.

    Thanks!
