    Can't help you with #1, but the answer to #2 is "nothing".

    In fact, the drive must be raw. If it's initialized or otherwise readable by Windows, DvrBARS won't write to it (or even see it in its default setup).

    The VHD is of a Tivo drive. You can use 'dd' if you know what you're doing. That is, you can not directly because all the sectors are scrambled around.

    Typical Linux does not speak Tivo partition maps, so it will never show you the partitions unless you use specialized Tivo-aware tools.

    tivopart, pmdmp, mfstools, jmfs, etc.
    hexdump -C is my favorite in a pinch.

    My 748 image shouldn't need a C&DE because it was taken from a factory drive that was never booted. If I'm wrong and you have to clear it the THX video will be deleted.

    What size drive do you now support for Premiere and Premiere XL? 6TB? 4TB? 2TB?

    DvrBARS should be able to write to anything, but it can only image drives up to 2TB. That's a limitation of the VHD file format.

    On a unformatted WD 1TB drive trying to restore image of the original 320GB drive the program showed reporting different file systems each time I tried it.
    There was one more I didn't take a screen shot of, it was labeled as 'Windows MFS' I believe.

    It's a new drive, I ran the long test and it passed. Any idea what is going on? The drive doesn't show in Windows, & shows unformatted in G Parted & Mini Tool Partition Wizard.

    The first pic you chose the drive as a source drive and since it does not have an MFS put on it, it gives you that error.

    The middle pic looks correct. And looks like it has a TiVo system on it at that time.

    The last screen states that the drive you are trying to restore to is mounted by Windows. However, the drives listed are Seagate drives and not WD.

    The 1st shot was the wrong pic, I didn't catch that nor noticed the last pic wasn't the correct drive. I don't remember what the exact situation was at the time, but I'm surprised I didn't catch that. The correct drive should of showed up.

    If only this program was used to image the orignal 320GB drive, then restore that to a 2TB drive (other tyhen the size difference) would or should it at least boot the Premier, probably only showing 320GB of usable space?)

    I have a problem with this. I run W7 on two bootable drives (one for backup). On one bootable drive, DVRBars crashes (APPCRASH) )when it is 'analyzing' the 320 GB TiVo source drive. On my other bootable drive, the program completes and image is saved. I restored that 320GB image to a larger drive (I tried a 1TB and a 2TB), but the Premier will not boot to it, it just re-boots back into the initial internal start up screen.

    I have to assume there is a problem with both O/S's though in somewhat different areas. The question is, what processes, programs etc. does DVRBars use of W7 to make it work?

    The source drive is a good source and the target is a good target. The source had just a TinyTiVo image.

    Hey there,

    Is there any way that you could send me a link to an image for a TCD746320?

    I am trying to fix my parents premier with a new Hard Drive, but JMFS is showing quite a few errors, was splitting errors, and is now on retrying error blocks...it's not looking good. I am thinking that I need to use a blank image of the Tivo software on the new drive. But with this in mind, I would now have to re-format the new drive using NTFS since i will be halting the JMFS process.

    Thanks!
    Bill

    The new drive needs to be blank, not NTFS, or FAT, FAT32, to begin with.

    It uses the WMI layer to build the list of available drives when you first start the program, but after that it's just reading or writing the selected drive using standard Windows calls like CreateFile, ReadFile & WriteFile. It doesn't even use the built-in support for VHD files on Windows 7 since I wanted it to be able to run on XP.

    It shouldn't even be possible for an APPCRASH to occur at that point without getting an error message from DvrBARS itself. I would try disabling any antivirus first, then start looking for possible disk driver issues.

    Since you have W7, one way to test it would be to mount one of my images in read-only mode in Disk Manager so that it looks like a physical drive to DvrBARS. It sounds like you aren't trying to save any settings or recordings, so the easiest fix is probably to just restore one of my working images to the new drive. Let me know what model number it is and I'll send you a link.

    No active A/V running (it's disabled by design).
    Would this run in safe mode?

    On that other drive, the fact the process did complete, but the image when restored to another drive wouldn't boot, you think it would still be "disk driver issues"? :confused:

    I was finally successfully (with jmbach's help) using MFSTool 3.2 to copy from a 320 to a 2TB drive, but I wanted to have a file version of that image in addition to the original HDD.

    It should run in safe mode, but I've never tried it. As noted, there's not much dependance on Windows itself except the WMI layer on the initial drive scan, and that's a core feature.

    As regards your multiple boot drive issues, I just dunno. It isn't a scenario that I have ever explored. One of my PCs multi-boots to XP/7 and the other one is 7/8.1 (soon to be 8.1/10), but in both cases the redundancy factor is provided by a hardware RAID0.

    I ran it again (not in safe mode yet). The 1st time it locked up, the 2nd try was able to scan the drive.
    It still didn't work, the new restored image to the spare 1TB drive (that was cleaned) just went into that starting up loop after 45 seconds.

    I'll try Safe Mode next.

    It looks like the error code is c00..05 which usually means the program is denied access to something it wants.

    With typical M$ error codes it could be almost anything. But, that doesn't account for the times where it did not lock up. Actually the program reports "not responding" after 20-30 seconds.
