    PM sent. DvrBARS doesn't do any expansion.

    To get it up to 4TB, see jmbach's thread.

    I went a different route on my 748 by putting a factory 758 image on a 2TB drive. I modified the "brev=" value in Block0, put it in the TiVo to update, then imaged it again. After creating another blank 2TB virtual drive I set up a VMWare virtual machine connected to both VHDs and used jmfs to add the second drive. After that I copied both virtual drives to the appropriate locations on a 4TB drive and edited the partition table and MFS superblock.

    Any chance you could detail this procedure a bit more? I'm thinking I need to do something like this to go from a 320gb factory to a 4TB.

    I don't know for sure that a TCD746320 will run a 758 image without any issues. My 748 didn't blink an eye (with or without the Block0 mods). The 758 image was taken from a factory never-booted drive, so it's still on the 14.5 OS. During the inevitable update to 20.x it downloads the appropriate software for the actual model and the System Information screen reflects that, but there are still traces of the previous model in some of the MFS files.

    If you have a 2TB drive handy in addition to the eventual 4TB destination drive send me a PM and I'll try to walk you through the rest. You'll also need Windows 7 or higher and VMWare Workstation.

    I'll be back later this afternoon. I need to get my lost count up before I can PM. I don't have a 2TB drive but I do have a spare 3TB wd red drive I can hopefully use as an intermediary. I use we can use hdparm to make it look like a 2TB.

    I've got Windows 7 and virtualbox. Is vmware specifically needed?

    Just to give some background of what I'm attempting versus what I'm starting with, I have a TCD746320 with the used, original 320gb drive. It's running the latest 20.x software. I want to replace the original 320gb drive to the 4TB WD40EZRX (green) drive I have. The original 320gb has never been tampered with. I have a backup of it's current state doing a Modified Full Backup using DvrBARS.

    It looks like Virtualbox can mount VHD files, so I imagine using that should be just as good as VMWare unless you had a specific reason that's a better option. As an intermediary drive, I have a spare 3TB WD (red). I haven't connected it to anything yet. Hopefully that will be satisfactory to use for this process.

    If I understand your original methodology, I would have the original VHD backup, create a blank 2TB VHD on the 3TB drive and have the eventual 4TB destination drive physically connected. All 3 drives would be connected to the VM (booting JMFS?) - 320gb VHD, 2TB VHD, 4TB physical.

    I apologize for all the short responses to get my post count to 10 to PM. I appreciate any and all help to get this accomplished. I intend to do the same thing on my TCD746500.

    I'm about to do a backup and restore for my 2tb XL4. Will be doing a modified restore and my disc is about 60% full. Will permanently delete recently deleted files.

    I will be using an external drive case using an Esata connection. In order to plan this out to minimize problems with the TiVo being down, can someone give me an idea roughly how long the back up and restore steps will take?

    The first goal would be to create a 2TB drive based on the 758 image and let it update in the TiVo to the latest software. Until the OS is updated it won't even boot on a larger drive even though the partition table is only using 2TB of the available space. I started my 4TB upgrade with an image of the original 758 drive running on a WD20EURS.

    The second virtual drive would be created with Disk Manager on Windows 7 or later. I don't know virtualbox, but if it talks VHD files it should work.

    After that we get to the complicated bits...

    Is there a need to start with a 758 image if I have the factory 746 drive and it's going back in the same 746? That image already has the latest software since its in use.

    Not at all. I just started there because my 748 was already running the 758 image to see if it worked. It's a handy starting point due to the 2TB factory layout and 4K alignment.

    See jmbach's 3TB thread for details. The process will be similar. Expand to 2TB and coalesce partitions back down to 14, then expand into the remaining space.

    I succeeded in reviving my Premiere XL with your tool. Thanks so much. I have also expanded with JMFS to 2 TB. I have not succeeded in getting the WD Align tool to work on the drive though. I find the instructions her daunting. If anyone has a cheat sheet on how to accomplish thin on an existing drive I would like to see it. Perhaps you might consider integrating JMFS and an Align function or streamlining the process? I made a small donation to the cause. Thanks again.

    WD Align tool does not recognize the TiVo partition structure so it will not work. There is a tool that will copy and align the drive. (the tool is found in the 4TB DIY thread or in the 320GB > 1TB > 2TB thread) it will align during the copy process from one drive to another.

    Would that tool work for the original S3 OLED except for the JMFS expansion (alignment that is going from 1TB to 2TB) and would WinMFS then be able to expand the resulting drive?

    I now have a good replacement drive and I'm ready to clone my HDD. However, I'm worried that I may copy some bad data, stuff that is causing problems on the HDD, and I'll just end up with the same problems on the cloned drive. If that happens, can I use the new drive to simply put an image on it after erasing the drive or whatever is appropriate. I'm not sure how to "erase" the drive if that would work.

    I believe it will and it should not affect WinMFS operation.
