    I don't have an image for that model, but I sent you a PM to the TCD746320 image. You can use jmfs to expand into the rest of the space on a 500GB drive.

    I just completed a upgrade to a 4TB hard drive on my TDC750500 and it is working.
    Only thing is it shows 429 HD hours and 3749 SD hours.
    I did the upgrade using JMFS104 and then installing it in the TIVO then after a complete run I removed it and did the expand and super size the drive using JMFS104.
    I think it still hasn't used the complete 4TB hard drive which is a WD WD40EZRX.
    Does anyone have a idea what I might do to get the full drive capacity?

    3TB and 4TB Premieres are still in their infancy, and the existing tools can't get you there without some fairly serious hacking. I just got my first one running a few hours ago.

    The procedure is entirely jmbach's baby, and he's working to come up with a new version of jmfs to make it user-friendly. Right now it involves multiple drives, a hex editor, and lots of MFS know-how. A full expansion to 4TB should show an estimated 640/5608 hours.

    Using your program now to back up a hard drive. Pretty sweet!

    Fortunately I have been able to contact Comer and we are discussing modifications and improvements to JMFS.

    We need to lock you, comer, and ggieseke in a room together, and tiger and spike as well if we could find them, and let you create the ultimate all-models does everything TiVo hacking package.

    :D

    Keep going jmbach - the 3TB & 4TB Premiere upgrades are AMAZING gifts I received thanks to your hard work on it :up: And I couldn't agree more with unitron's comment about locking you, ggieseke, comer, etc. in a room to come up with an amazing automated tool for all TiVo DIY-ers :)

    The beer bill for that meeting would probably cost more than a new Roamio. :rolleyes:

    At this point JMFS will expand it to about 2.2TB so you have a proximately 2.7TB of recording space. If you are wanting to get 4TB you will have to expand it to 2TB first, be willing to copy the partitions over to a 4TB drive, rearranging the partition to be able to coalesce at least 2 partitions into one, and either wait for a new JMFS to come out (which hopefully will be in the near future) or be willing to try this procedure I have developed.

    I think I will wait for the JMFS upgrade. That sounds like the best way to do the upgrade to 4TB HD. Thank you for your interest in this upgrade.

    Not a problem. I did post the upgrade procedure here DIY 4TB Premiere if you want to see what is involved.

    Just tried 'Truncate' with a nearly full drive from a Premiere. It completed a few hours later, giving me a file a little over 400Gb in size. I was expecting something smaller. Where did I go wrong?

    {further clarification: this was a 75 hour Premiere with the original factory drive}

    I just did the same thing and the size was ~99Gb, I thought something did not seem right.

    It seems that something changed in 20.3.8 OS that causes DvrBARS truncated backup size to be significantly larger than in previous OS versions.

    Hi Greg,

    I've got a WD20EURS plugged into my system (on an internal SATA port). When I run DVRBARS I'm getting:

    Error 0x00000001 (1): \\.\C: DeviceIoControl IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS

    FYI, C: is my boot drive. It's a regular XP install - not a restored image, etc. Also, it is a 1TB drive partitioned into 4 (relatively) equal parts, each formatted NTFS. Furthermore, the BIOS for this machine is set to "IDE" for compatibility.

    This machine also has a floppy drive that is A:\ and a DVD burner that is D:\ (internal SATA) [I unplugged both of those, no change.]

    I'm running Windows XP on this machine, but I'm guessing that should be fine since you said it supports XP.

    Device manager sees the new Tivo drive (I did not let it format/etc.)

    Any ideas?

    Cox Cable...
    I've been able to eliminate this "variance" by performing a "Clear Program Information and To Do List", prior to the backup (and keeping the network cable unplugged during and after the process, to prevent repopulation).

    While the "and To Do List" part may sound scary, the Season Passes and ARWL entries WILL repopulate once the guide data has been re-downloaded. You WILL LOSE any manually scheduled entries and non-AR WishLists.

    Having the supersize option enabled tends to be a large contributor to the variance, but gets nullified (mostly) if you jettison the guide data.

    I can't quote sizes, since my Premieres have all been sold-off. But, I did verify the data I just posted with 20.3.8.

    Don't forget that the DVRBARS files will often zip/rar compress down GREATLY, if you are trying to back-up to DVDs or thumb drives. I've never seen a case where no additional compression could be applied.

    EDIT/ADD: The variance will also tend to be different, depending on which methods/tools (and/or image) was used to create your larger-capacity upgraded drive.

    I noticed the same variance while creating a 4TB XL using jmbach's method, but I thought it may have been a one-time glitch. I started with 20.3.7.1a and the truncated image was about 1.7GB as expected. I let it upgrade to 20.3.8, repeated the process, and the truncated image was only slightly smaller than a Modified Full.

    I'll have to extract and analyze the MFS on 20.3.8 to see what's up. Somewhere along the way from 14.5 to later versions they switched from /Recording to /RecordingLite but it still worked as expected since I was excluding anything that started with /Recording from truncated backups.

    Sorry about that folks.

    Hmm. Error code 1 is defined as ERROR_INVALID_FUNCTION, which I haven't seen before. Are you running any kind of underlying partition manager or compression software on that PC?

    If you don't have another computer you could try let me know and I'll write a customized version for you that ignores that particular error, but it's definitely strange. I could understand a NOT_READY or GEN_FAILURE code, but it seems to be saying that the IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS function doesn't exist.

    Here's some info on that function.
