    jmfs was designed for Premieres, but "happens" to work on Tivo HDs..

    I've never used WinMFS (I don't have a Windows machine), but jmfs is a simplified way of upgrading, IMHO. Basically, it's a nice interface on top of the existing command line tools, I think.

    Since you're not really upgrading, simply replacing a failing drive with one which is more than likely exactly the same size, you just need to use ddrescue, a standard linux command (it is on the JMFS boot disk) to make an exact copy of the drive.

    JMFS works with any Tivo even Premieres, it only does a drive to drive copy, no backups.
    WinMFS does not work on Premieres.
    You can also look at a newly developed, DVRBars, it does backups of nearly all Tivos including Premiere and it does not do drive to drive copy (yet).

    jmfs will not recognize anything older than an S3 HD drive as a TiVo drive, so original S3s, S2s, and S1s cannot use it.

    Is there any program that will make a backup of my TIVo (S3 OLED) Hard Drive without me having to remove the Hard Drive? I'd love to have one just in case. It doesn't even need to have the actual Shows. Just the OS and personal settings for the Cable Co.

    But, you can still boot with it, then drop to the command line and manually use dd_rescue. As long as you know how to, or do your research first on "GNU dd_rescue".

    If the drive is starting to fail and you want to preserve your programs, I prefer the way JMFS does the copy. If you go to a larger drive, use JMFS for the copy and WinMFS for the expand and supersize (if it isn't already and you'd like the extra space).

    I believe it's technically possible, but not in a way that can be discussed here.

    I haven't been to the "other" site lately, but as a programmer involved in writing TiVo backup software I'd love a hint. At this point I can't imagine a way to pull off a backup without cracking the case and hooking the drive up to a separate computer of some kind.

    It's been a couple of years since I pulled a hard drive out of a TiVo. What's the easiest method to get a simple backup now? Is there a way to do it on Mac OS yet or does one still need a Windows Variant?

    I sure thought that whatever Linux CLI tools used to make a backup have also been compiled on Macs.. I think I even did it a few years ago.. I'm even more sure that I did a S3 upgrade on a Mac with Mac compiled tools.

    Of course you can use MAC HARDWARE and boot from the Linux CD, e.g. jmfs for TivoHD/Premiere upgrades.. or the Linux boot CD.. Just make sure you know where your hard drives are in Linux!!

    Hey... You live in Sunnyvale right? I'm in Cupertino. Think I could talk you into helping me do it some time? There's a couple cases of beer in it for you (or Pizzas if you prefer). No pressure, but it would sure be nice to have someone here who has actually done it recently.

    We only have Macs here now and I don't have Windows installed on any of our Macs. So you may need to bring your laptop too. :p

    I'm not certain it's possible, but I don't know for sure that it's not possible, either.

    I imagine TiVo's own developers/programmers must've required a remote client service installed on the OS. It may be more secure than Fort Knox, but if it's there at all, 'they' at least probably have the ability to read all of the disk remotely - making a remote backup possible.

    Whether or not such a capability could ever be tapped by anyone else would be a major hurdle by itself. If there is no such service already installed, any hope of success would certainly rely on installing one, which is probably not possible.

    No matter what, it's gotta be much simpler to just pull the drive and do the backup that way.

    I can't say how I know. But I do know, for fact, that TiVo can take a drive that has been pulled from a TiVo, shipped into them, and extract/decode the recordings in their "lab". But, I'm sure we all know that they can. The question is can we replicate that. That question is a slippery slope on here. Any discussion of hacking or decrypting content that was intended to remain encrypted, outside of normal use, or means made available by TiVo to us, could be considered discussing something along the lines of unprotecting protected content. Don't discuss it here. Take that kind of discussion over to d****d***b***dot com instead.

    If that's not the aim, well, no harm, no foul...

    just to let people know how the story ended, I put both drives in my PC and booted up the jmfs CD. I selected the "Copy" menu option. It said it was about to copy 1TB of data from my wd10evds to my wd10eurx drive. 9 hours later it was done and I exited the program (no expand or supersize was done). Put the wd10eurx in my tivo and everything was there and working (so far, knock on wood :).
    Thanks to all for help and advice

    ggieseke: Quick question as I plan on setting up a new WD20EURS for a used S3 (TCD648250B). I pulled down the WinMFS image from unitron and have the new drive coming tomorrow (the S3 arrives on Wed). Since I don't have any recordings that I need to transfer from the drive that is coming in the S3, are there any precautions I have to take when "restoring" the image to the new 2TB drive? Three questions specifically:

    1) When "restoring" using WinMFS, do I need to change the default "swap size?" mfslive.org/winmfs/images/mfsrestore.jpg

    2) Should I press YES or NO to "do you want to expand?" I plan on running MfsAdd and MfsSupersize afterwards.

    3) Do I have to worry about any of the additional iBored steps Lussie wrote about here: tivocommunity.com/tivo-vb/showthread.php?p=9168233#post9168233

    Thanks so much in advance!

    You do not have to use iBored for anything. When I expanded mine I said to to expand after copy. I did use a larger swap size but there is no evidence that it makes much of a difference on an S3. Most people usually feel that it won't hurt and can only help. I used 1024mb while others 512mb. FWIW, the 2TB premiere XL4 drives only use 128mb. I did use an optimized partition layout. When using MFSAdd make sure you answer correctly to not limit the expansion size to 1TB.

    Thanks jmbach! Looks like I'll try cloning the 1Tb drive first to avoid having to deal with error 51 when using someone else's image.

    Another day, another broken S3 OLED Tivo. After having it pulled from the rack weeks ago I finally cracked it open, and yup, a bad C701 capacitor. I've previously repaired my Mitsubishi TV years ago with bad caps so I think I can do this pretty easily. I've ordered the parts and we'll see how it goes.
