    Not at all, what's being said is that with 11.0k you can now use WinMFS on a single 648 drive and expand it to 2.0TB bypassing the previous 1.2TB limit, no JMFS needed.

    jmfs DOES NOT work with the 648 because it won't or can't detect the 648 drive as a TiVo drive.

    At least it couldn't a few weeks ago when I tried it just for the heck of it.

    Try it with the MFS Live cd and see if it'll create a partition larger than 1.2TB.

    So I have a lot of options available, but which would be easiest in the long run?
    I can let my 250GB update to 11.0k, back it up, then restore it to the 2TB but not expand, make sure it's happy, then pull it out and do an expand.
    I could take my 648 TBK, (older than 11.0k) put it on the 2TB, let it update to 11.0k, then pull it and expand it.

    I'm option to options since I have some time to plan this.

    What are you running in that 648 right now?

    2x 1.0TB drives, as far as I know that means I'm SOL because they're striped and I don't want to divorce them in case I have to go back because the 2TB doesn't work out.

    I really like the idea of backing up the data, pulling them as a pair, doing all my testing on the new 2TB and if it fails I can go back to the existing drives full of content.

    An experiment you could try is hooking up both drives to a PC (you might need an eSATA to SATA adapter) and seeing if WinMFS can make a truncated backup, which wouldn't have your recordings, but would have all your settings, season passes, thumb ratings, etc.

    Another interesting experiment would be to hook up both drives and a single 2TB and see if it will let you select both current drives as the A and B of the source and the 2TB as the target.

    I can do that..I thought it wasn't possible in the S3 with WinMFS but it's win/win since I lose no data and I have enough SATA ports in the test bed to do it.

    As far as I know WinMFS will treat the source drive(s) as read-only, and I certainly would expect spike to have taken care that it be so, but not having created it, I can't absolutely guarantee it.

    But if you try it, hurry back and tell us what happened.

    Combining the data from 2 drives to a single larger drive is possible. As, Dvr_dude offered such a service a couple of years ago, when I inquired for my 648250B.
    Unfortunately I do not know how he is moving the data.

    As I thought, WinMFS says it can't combine A and B to a new drive, says "not supported at this time"

    Ok, I let my original 250GB update to 11.0k,
    I used WinMFS and let it copy then expand, it said "hey you're going to make a partition bigger than 1TB, are you sure?" and unlike previous times I said "yes make a bigger than 1TB partition" was that the right thing to have done?

    I'm not 100% sure the machine is healthy since I'm not paring the CC's in this interim scenario. It shows 2512SD or 288HD hours, that sounds right? but it doesn't want to copy anything via the network at the moment.

    I've got a 648 with a WD20EURS and a 15th MFS Media partition that's 1.6TB in size.

    And a 1GB swap partition.

    I never bothered with supersizing.

    It sayeth Variable, up to 287 HD hours, or 2511 SD hours

    It's on analog cable and no antenna hooked up, if that matters to the numbers, although I suspect not.

    Sounds like mine is on the money, I didn't do anything special as far as swap file, should I have? it's not a big deal since this was a test, I still have to offload the existing shows from the 2x 1.0TB setup before making the move. It almost sounds like I know what I'm doing :)

    Yeah, I almost know what I'm doing to.

    The swap thing is just something I choose to do. Back in the breaking the 137GB barrier days of patched kernel S1s, it was considered necessary to go bigger than stock, in the event a GSOD had to be fixed, with a rule of thumb of 1MB for every 2GB of hard drive.

    It probably isn't necessary on newer embiggened TiVos, but I've never heard of it hurting anything, and at 15 minutes of video on a 2TB drive, I figure it's cheap insurance.

    But plenty of people have used jmfs to take a 320GB Premiere up to 2TB without changing the swap size, and I haven't heard of any of them having problems conclusively linked to insufficient swap size, so...

    Yer pays yer money, and yer takes yer cherce.

    I just put everything back the way it was, an S3 with 2x 1.0TB drives shows 318 HD / 2777 SD hours, same as the Weaknees upgrade drive, there's a chunk of space missing with the 2TB drive, almost 10%, that may be enough to have me scuttle this project.

    Did you supersize that 2TB?

    Yes, the space you are missing is from not supersizing the drive. Those look like the numbers of my 648 after expanding and before supersizing (287). Can't remember at this time the exact details but supersizing adds video time by reducing the space of something else. Unless someone else pipes in first, I'll look it up and get back to you on what that something else is.
