    The way I outlined earlier in this thread does all of that, plus saves the recipients time on waiting for the C&DE process to complete, and makes the cleanest & smallest image possible, while providing all of that.

    I guess since you seem sure your images won't leak into into the wild, I need not be concerned about what state the drive is in when you image it.

    It has been some years since I have done any images for anybody but myself (except ggieseke who does know what he is doing).

    Can you explain this DvrBARS behavior?

    11/26/13 - Truncated backup of my WD20EARX (from TIVO TCD746320) successful, size 3.62 GB

    8/2/14 - Same TIVO, same drive, same copy of DvrBARS (1.0.0.3), permanently deleted all of the Recently Deleted programs first and then successfully made a Truncated backup, size 106.4 GB.

    Why the huge size disparity? Is bigger, better?

    Will either of these truncated backups actually be able to create a functional 2TB TIVO drive?

    In my case I was able to copy my drive with JMFS, so I don't plan to use the DvrBARS restore functionality. But I have seen recent discussion of this issue on this thread, and want to report that permanently deleting the recently deleted files does not solve the problem.

    Do you TIVO gurus replace drives before they fail?

    Do you have any backup strategy?

    I have 2 TIVOs - an HD with 1TB and a Premiere with 2TB - which are primarily used to record shows from cable so that we can watch what we want, when we want, and avoid commercials. Unfortunately, if a TIVO drive fails, all it contains can be lost.

    The drives have been working well for 3 years, but I have decided to replace them both prophylactically. Is that crazy? One benefit is that the retired but functional drives are available to restore a new drive in the case of drive failure.

    Regarding backup, the TIVOs are located in separate viewing areas, but are set to record most of the same shows, so I have a backup if one were to fail. This system works pretty well, but can be foiled by TIVOs failure to explicitly notify you when a recording is skipped because it is of lower priority.

    I guess I'm willing to admit to my OCD tendencies. What do the rest of you do?

    I still don't have an explanation for that behavior. Running C&DE does bring it back down to the size that I would expect with either Truncated or Modified Full backups, but I guess the RD programs isn't where the problem lies. I proposed that as a possible solution a while back and you're the first person who has tried it and posted the results. Thanks.

    Both images should restore fine, it's just that the 106.4GB image is obviously way too big for a Truncated backup and includes sectors that it shouldn't.

    I had asked a similar question a while back but didn't get much in the way of responses. My current 2 S3 OLED's both have 1TB drives that are 6 years old now. I too had thought of replacing them before they failed with new 2TB drives.

    Looks like this forum would be quite helpful in figuring out how to fix (or replace) the hard drive in my TCD748000. But, where do I find an image file to use once I crack it open? Are there links anywhere? Thanks.

    None of my 2TB WD "green" AV drives have died yet, but I've had 2 "Caviar Green" WD20EADS drives (which I was running in a PC running Desktop and backing up shows to) go bad shortly after end of warranty, so If you can spare the money, I'd call it good practice.

    And it'll give you an excuse to move that HD up to 2TB.

    I just backed up my 2tb drive in my XL4 this morning. Used the truncated option and was about to tack it onto my desktop until I saw it was something like 1.5 tb and wouldn't fit on my 1tb OS drive. Fortunately I have another 3tb drive in the PC with plenty of room. I was hoping to also put the image on a flash drive for safe keeping, but obviously that is now out if the question.

    I am now waiting out a full restore to a 2tb drive. I did full as I previously tried to do a restore on it in the past (bad external enclosure was fouling things up) and figured I'd play it safe and write zeros on unused parts.

    Once the restore us done, I will put it in the TiVo to make are it boots up okay. Is there anything I need to do to make sure it is ready to be fully functional with full capacity in the TiVo if and when I need it should my existing drive have a problem?

    It's been my experience that a WD20EADS drive, running 24/7/365 for three years, will never spin up again, if powered off.

    I've seen spindle motor lockup, head to platter seizing, and inability to spin-up in time before the drive aborts and tries again (over and over).

    Even though it's outdated advice to stick a drive in the freezer, I've tried it a few times over the years (as a last resort), and can say it's been almost 10 years since the "hard drive in the freezer" method made a drive work again, for me, in any capacity.

    There are far too many problems that that method can cause, and just make things worse, or create more problems (often taking any other valid methods off the table). Cooling the PCB can be done a number of ways, that don't create condensation. Even if sealed in a bag, with sealed cables coming out of the bag, there's still moisture in the air inside the drive, and what air is in the bag, even in the mojave desert.

    In my recent experiences, when running 24/7, standard drives would last 2 years, and the AV ones 3 years (about the same length as the warranty). Anything longer is good luck, and gravy.

    At some point, something changed with the drives and longevity. I still have a drive that is over 15 years old, ran 24/7 for about 10 years, was retired, but still powers-up, works, and passes all the tests I can throw at it. It sounds like a circular saw cutting through plywood, but just won't quit. 80GB WD Caviar 7200RPM PATA (the WD Black of the time period).

    My new method is to test for slow-reading sectors that would cause AV issues, but not fail a test. I then word my RMA request to reflect that the drive has too many slow sectors to keep up with what I use it for. So far, that's worked well for me, when I have a drive close to warranty, that hasn't failed.

    WD has just recently changed their whole RMA "Support Portal", and everything about registration & RMAs, so I have no idea if I could do that anymore...

    I still have two stock 160GB drives, from some of the first TiVo HDs to go to retail, which don't work fast enough for TiVo use any more, but pass all standard tests with flying colors. I should run them through Spinrite testing and see what that level of testing says about them...

    If the existing drive was already using the entire 2TB it should be fine. I don't resize or move partitions like WinMFS. Every byte that it backs up gets written to the exact same location during a restore. You can check the hours on the SI screen to be sure.

    I gotta figure out why truncated backups are picking up so much extra stuff. :(

    Okay, here is what I noticed/did. While the backup said the file was 1.5tb and showed that when I clicked on properties afterward, I notice that checking the properties of the drive itself did not jive- by subtraction the file wasn't anything near that.

    When I put the drive with the restore in the Tivo it still showed the listing of all the shows and the drive 50% full. The shows of course weren't there and I got an error when I tried to play them. I deleted all the shows to get down to zero disc usage.

    I pulled the drive and ran a backup from it and the file size then was only about 2.7gb- a number I assume would be expected.

    An interesting thing I noted was that the THX video WAS playable so apparently it is somewhere on that "truncated" area.

    Greg, I am in awe of the work you and others do to help amateurs like myself deal with their TiVos. I made a modest contribution via Paypal.

    That's really interesting. How big was the actual backup file? I knew that a C&DE would get it back down to size, but your results are a first. About 2.7GB is pretty normal for a raw Premiere image and that should zip down to about 1.5GB, which is definitely flash drive or single-layer DVD territory.

    It should keep all of your your settings and maybe even the CableCARD pairing if the gods are smiling.

    I specifically wrote it to include the THX video and the two "intro" videos that came with 14.5 in a truncated backup. Glad to hear that's still working.

    Somewhere in the early 20s (software-wise) they dropped the /Recording folder in MFS and all of its subfolders and switched to a single /Recordings folder with just enough info to point to the SQLite database for the rest of the metadata. The truncated backup code still worked as expected back then because I was looking for any folder that started with "/Recording" and "/Recordings" fit the bill. They have probably changed the landscape again and that's why it's making huge truncated backups.

    Most people don't have the disk space to even attempt a nearly 2TB backup file, so your feedback really helps. Your donation is also greatly appreciated. :D

    As I said, DVRBars said it was 1.5tb at the beginning of the backup process. When I hit properties on the the .vhd file after the backup was complete, it said it was 1.5tb in size. However, my 2.7tb HDD already had 0.8tb on it leaving roughly 1.9tb free. After I put the .VHD on it and then hit properties of the HDD, it still showed about 1.9tb free space. Thus while the .vhd THINKS it is 1.5tb in size, it obviously isn't.

    I suspect that if I had tried to put the first "1.5tb" .vhd on the desktop of my OS drive, even though there wasn't 1.5tb space available for the .vhd, it would have worked just fine.

    I read some many postings about backup and restore but never get a clear statement about these 2 questions:

    1) If I have 2 TiVo units of the same series (e.g. TCD746320 and TCD746500), can I restore a backup from one unit (smaller or equal size) onto another?

    2) Will the unit being written retain its unique TiVo Service Number (TSN)?

    I would guess the "master" TSN is from its ROM but also know that the TSN is saved in various files of the hard drive.

    Thanks

    Yes as long as the drive you are restoring to is of equal or larger size than the image you backed up. If the drive is larger, you will have to expand it with JMFS to use the whole drive for recording.

    Yes, but the image will show the TSN as all zeroes until you do a C&DE.

    Hey Guys ..

    My drive is starting to act up and I might need to do a reinstall and wanted to see if this might be available if I need to do to a total swap.

    I'm on Win 8.1 and tried using DVRBars but it starts then stops immediately - I've tried compatibility mode with no luck.

    I can try to use my original drive and do a clone of some kind, but don't know if that's my issue (bad sectors) - planning on running a 54 disk-check overnight tonight.

    Thanks in advance - trying to get out ahead of a bad HDD and the related downtime - happy wife, happy life!

    dave.

    Did you start DVRBars via "Run as administrator"?
