    I did it! I'm now the proud owner of a 2TB Premiere. I went from a 96% full disk to 15% full.

    I used comer's tool and it worked with out a glitch! I had a few issues getting Sun's java on a ubuntu live CD, but after that all was good. The tool doesn't work with the openjdk java that comes with ubuntu.

    Just one question for comer. Whenever the 3TB drives come out will I be able to copy my new 2TB to a 3TB disk and use your tool again, or will I have to go back to the original drive.


    Thanks again for your work!

    Is there any way you can make the Ubuntu live CD with Sun's java available? That would be a huge help.

    Failing that, can you detail the steps to get Sun's java on the CD?

    Thanks,

    Ed

    Congratulations! :) And thank you for giving it a shot ;)

    Running tool multiple times - is the area where we need more testing in general. I suspect it won't sit well with Tivo. However, I am developing (well, almost done) another resizing tool, that "(enlarge or shrink) any given partition, perhaps representing the holy grail of mfstools: mfs_resize" as someone said ;) No shrink though. That is - resize without creating any new data structure. That would work together with the current tool - because a partition in Tivo is limited to 2T, but resizing one and adding another would be able to accomodate up to 4T. Again, this is a theory :)

    I just used the ubuntu install CD that you can download from ubuntu.com and ran ubuntu from the CD instead of installing it. Whatever you install is just in memory and is gone when you reboot.
    After its running go under the menu System/Administration/Software Sources and check the box for "Main" then click update.
    Then I used the steps shown here.
    http://www.ubuntugeek.com/how-insta...vironment-jre-in-ubuntu-10-04-lucid-lynx.html
    Except the last step didn't work, so I had to finish installing it by running "Synaptic Package Manager" under the Applications menu I think. I found a reference that here: http://www.clickonf5.org/linux/how-install-sun-java-ubuntu-1004-lts/7777

    I sort of had to piece it together as I went with a little help from google.

    If you just run off the CD you don't need to install anything on your computer and its all gone when your done. Thats both good and bad I wish I had a copy that was ready to go. :)

    Thanks for the feedback.

    One thing that confuses me though is this: If you run off a cd which is presumably read only, how would java ever be installed?

    Thanks,

    Ed

    P.S. I'm gonna give it a shot!

    It creates a ramdisk, which is read/writable.

    Good luck! :up:

    Excellent! Kudos to comer.

    Now I can experiment if I ever come across a Premiere on the cheap. :up:

    Agreed! My Premiere XL's 1TB drive is around 85% full so I could use some more space pretty soon. Sounds like there are a few bugs to be worked out, but I think I'll jump in when the time is right! :up:

    Comer talks about making a backup image of the Premiere drive, which I'd like to do. I haven't worked on a TiVo in a while, but I have upgraded drives before (I'm a little rusty) Would someone be kind enough to point me at the right directions for creating an image of the Premiere drive? Should I use the MFS tools as shown here: (http://www.mfslive.org/winmfs/quickstart.htm#backup_restore)

    Thanks in advance everyone! My 2TB drive should arrive Monday and I can't wait to upgrade!

    thanks for the development comer.

    I have a feeling you and spike are *very close* to a mfslive-type solution. ;)

    If I have been reading right, you need to expand the drive comer's way.

    Start here:

    edit:

    If all you want to do is make an image of the drive, all you need is 'dd' or 'ddrescue', IIRC.

    Thanks Steve. Can you tell me the exact command I'd use w/ddrescue to make the image?

    Hi,

    I'm just getting started trying Comer's upgrade (thank you!).

    I opened my Premier and was surprised to see the drive was installed upside down.

    Are they all like this? Is it OK for them to be upside down?

    Thanks,


    Ed

    First, you need to have read permission for source drive and write permission for target. So do it as root or sudo.

    Important: the specied ouput file/device will be completely rewritten, so make sure input and output specified correctly (not mixed up).
    As a precaution I always make the source read-only, just in case (chmod u-w,g-w,o-w <tivo drive>)

    For dd:
    dd if=<tivo drive> of=<image file name or another drive>
    e.g. "dd if=/dev/sda of=tivo_disk.img"
    If you want to compress it on the fly (virgin drive compresses A LOT because it is mostly zeroes) make dd outputif to sdout and pipe it into zip:
    dd if=<tivo drive> | bzip2 -c9 ><compressed image name>
    e.g. "dd if=/dev/sda | bzip2 -c9 >tivo_image.img.bz2"

    dd is silent, so you won't see a progress, unless you send USR1 signal to it (like kill -USR1 <dd pid>).

    For ddrescue
    ddrescue -r 3 -v <tivo drive> <image file name or another drive>

    e.g. "ddrescue -r 3 -v /dev/sda tivo_image.img"

    ddrescue gives out nice interactive progress, but can not compress on the fly.

    It's a good idea to look up the manufacturer's tech specs as above. I've seen some (older Seagate?) that said it could be installed in any orientation except label side down.
