    The full restore still might be a good idea. If the password is located in an area that is usually null, without a complete restore it might remain and if the Tivo just checks to see if it is not null to activate parental controls, it will still be active.

    O.k. just one last post to close the loop on my prior posts, thank you all and confirm you were completely correct in the comcast cable card pairing problem diagnosis.

    Sadly I simply could not get comcast to fix remotely and they insisted on a truck roll. Appointment was a week wait. I called them several more times with "leads" while waiting but nothing ever came of these calls. Finally appt day came. At noon I get a call from tech saying, "those cards from the service center don't work, you need special tivo compatible ones and new ones that haven't been used before...I don't have them now. Will get tonight or tomorrow. " He gives me his personal cell number. Day later he says he has and will come out next day. Next day, he never shows. I text him several times. he replies to none of these. Doesn't tell me he's not coming or anything. Call Comcast and they say, sorry, we can't tell you when we can get you a tech - can you call back in a couple hours to try again (at 1:00 a.m.) ? I hung up. (Caveat, we did have a major storm with possible tornados and major outages so I understand this a bit.) 2 things I did next. 1 - I had opted in to customer sat survey post call. I won't describe my ratings (PG forum I think), but at the end they asked if I wanted to be called back about my problem. I said yes and detailed all the above, very nicely and said in an exasperated tone that I'd really like to get this fixed. 2 - I filed an FCC complaint against comcast here saying I suspected they were running afoul of cable card regs: https://esupport.fcc.gov/ccmsforms/form2000.action?form_type=2000E

    It really wasn't a bad form at all.
    Next day, came home and voila, everything was working. You KNEW they could fix it remotely, I knew they could too. ARGGGH. !@$!#%!#%!@#%
    Anyway, thank you all so much once again. Great Forum! Great people!

    Thanks for helping me out with the image - glad you had it! It is fine for me to wipe out the drive as I bought it from someone and don't need anything on it. I think the problem and reason TiVo support couldn't get it done is that the unit is not connecting to TiVo and I can't configure the network without the parent controls password. They said to leave the unit on so they could send something to it overnight, but I am sure this didn't work because the network is not setup properly.

    I probably won't get to try this out until after the weekend, but I will let you know how it goes.

    Thanks,
    Rich

    Would it be possible to copy my Premiere XL (2 tuner) drive with recordings etc. to a 2TB drive and pop it into a TP4?

    I haven't powered on the TP4 yet.

    Thanks

    Yes, but you will lost the recordings. You would have to marry the drive to the Tivo with Clear & Delete Everything.

    Thanks for the speedy reply.

    I was looking for a way to keep the recordings and season passes. Any utilities developed to copy from an old unit to a new one, or just manually one at time?

    For the season passes, you can copy over using your tivo.com account, season pass manager.

    Recordings, only way would be to transfer over either to a PC and then to the new Tivo or from 1 subscribed Tivo to another subscribed Tivo.

    My experience:

    1. Full backup of a fresh TiVo TCD750500 Premiere 4 Drive (DvrBARS)
    2. Quick Restore to a WD20EURS (DvrBARS)
    3. Expand using JMFS
    4. Supersize using JMFS

    Yielded a 318 hour TP4. I actually used the same backup to restore to two drives, one for each of my new machines. I had to do a clear and delete on one of them to get the ESN active.

    Now make a backup of the 2Tb drive using DvrBARS and if someday you have to replace the drive you will only have one step to do, make the smallest backup.

    I just redid my Premiere drive, from the well-used image here. Did all the updates, got the cable-card recognized again, clear and delete and got my lineups all set.
    When I then pulled the drive from the Premiere to make a backup in DvrBARS, the PC can't see the drive, whether it's via USB or SATA connection.
    What could I be doing wrong?

    Are you using administrator login? Do not let your system try to read the drive, it can't, only the software such as DVRBars, WinMFS, etc. (with administrator rights).

    hi - yes, I have administrator rights. All I get is "no useable drives found"

    I did run Kickstart on the drive from within the Tivo before trying to backup in DvrBARS. Would that mess up the formatting somehow?

    EDIT: OK, ran DvrBARS on a different PC, and it found the Tivo drive. Weird - no idea... lol

    OK, now I'm confused. Based on this:

    There are three backup options (Full, Modified Full, and Truncated).

    Full is perfect if you have a drive that's straight from the factory because most of the drive is all zeroes. A Full backup "xeroxes" the entire drive, but due to the way dynamic VHD files work you'll get a byte-for-byte copy of the entire drive in a relatively small file. For Premieres that's usually about 2.5GB and you can zip it down even further.

    Modified Full backups selectively copy all of the sectors that are in use, including your recordings. You'll need a lot of disk space if you have a lot of recordings.

    Truncated backups are like Modified backups, but your recordings are excluded. The final backup file will be about the same size as a Full backup of a factory drive that has never been booted, especially if you exclude the alternate Root partition (see the Settings screen).....

    If I did a FULL backup of a 1tb drive that has absolutely NO recordings and is as fresh an install as possible (the only thing I did was a clear and delete and grabbed my TV Guide data), DvrBARS says that the FULL backup is 931 GB!! I thought I read it would be as little as 2-3GB.

    What am I missing? I don't have enough hard drive space for a 931GB backup.
    Is that just a theoretical number that will change once the backup starts?

    How do you create a drive that's "straight from the factory".....

    How much physical space would that take up on a drive, and WHAT kind of backup are you discussing here: Full, Modified or Truncated?
    Thanks

    For a Premiere, you can probably assume about 2GB for a truncated backup. A modified full backup would take that much space plus the size of any recordings (whatever that is).

    Full backups work fine on a drive that just came straight from the factory because 99% of it is all zeroes and it compresses well. You don't "create" it, you buy a brand-new TiVo and remove the drive before you even plug it in. In that case it will be almost identical to a truncated backup. Once the drive has seen any real use, a full backup could be larger than the actual drive size.

    A C&DE does not overwrite the unused parts of the drive with all zeroes. With a used drive, a truncated or modified full backup is what you want.

    You can shrink it a bit further by going into Settings and choosing not to back up the alternate OS partition.

    OK, thanks. I did a truncated, and it appeared on my PC drive as 7GB. No recordings - just a post-Tivo download of my cable companies info and guide data. I assume the smart thing to do after doing the truncated backup is then "restore" it to the drive it came from, just to make sure it worked?

    7GB sounds screwy to me, but if it completed a truncated backup you were backing up a TiVo drive and the file systems were intact. I've never seen one go over about 2.5GB.

    If you really want to test the image, use the Full Restore method. It will take forever because it writes zeroes to all the sectors on the drive that it didn't actually back up. Alternatively, you could do a quick restore to a different drive.

    That must have been one heck of a guide data download. :p

    yeah, I thought the same thing. 600 channels at two weeks listings = 5gb? I wouldn't know. I used the Premiere image from here to start (3.5gb), updated the Tivo software, did a clear & delete, and then downloaded the listing. End result = 7gb.

    But.....

    I just ran Truncated now, a second time, and got a file that was 2.8gb (?) - which included partitions 1-9 and partition 14. Does that make any sense?

    Can't I do a quick restore back to the drive from which it came?

    Sure, you can do a quick restore to the same drive but it won't prove beyond the shadow of a doubt that your backup is 100% reliable. In quick restore mode it only writes the sectors that it backed up and leaves the rest of the drive alone. If it did miss something critical (which I have never seen it do) you wouldn't know the difference because the rest of the drive wasn't modified in any way.

    2.8GB sounds a lot closer to what I'd expect depending on the exact model number, the operating system version, and whether you skipped the Alternate Root Partition.

    About the only thing I can think of to explain your previous 7GB backup is that it may have still been indexing the guide data. I have no idea how many temporary files it uses during that procedure.

    The partitions sound right. I only display the partition numbers for the Linux partitions because it scans the MFS partitions as one complete file system. On a typical Premiere that's 10-13.
