    OK, here's the steps thus far:
    1. Get a Knoppix CD.
    2. Download dd_rhelp from here (Kalysto.org)
    3. Put it on a USB drive.
    4. Hook up your drives (old/new) in the usual fashion; I did the old to primary master, new to primary slave, because stretching the IDE cable between the DVD drive and the HD drive bays always gives me fits...
    5. Boot the computer from the Knoppix disk (MAKE SURE YOU DISCONNECT YOUR WINDOWS DRIVE FIRST!!!)
    6. In Knoppix, untar dd_rhelp (tar xvzf dd_rhelp.tar.gz) from the command line (terminal in the lower left hand corner of the screen)
    7. copy the resulting dd_rhelp file to /bin/ (sudo cp /path/to/wherever/it/is /bin/); don't forget the trailing slash!
    8. type which ddr_help to make sure it's looking in the right place; it should come back with /bin/dd_rhelp
    9. sudo ddr_help /dev/hda /dev/hdb (in my case, make sure you've got the hd* letters right before you start, otherwise it's curtains for your data!)
    10. Wait and pray.

    Thanks I never have used dd_rhelp looks like a nice shell for dd_rescue I'll check it out and add it to my TiVo tool kit.

    JFWIW (you probably already know this) The copy will go a lot faster if you put the drives on separate cables and verify that DMA is enabled. IDE is mono direction Drive1 ->IDE-> CPU/ram ->IDE-> drive2. Having 2 IDE channels will almost double the transfer speed and getting the CPU out of the equation with DMA speeds up the transfer even more.

    Oh and you forgot
    cross your fingers, turn around 3 times CCW on left foot then watch Live TV and complain about it a lot :)

    Heh... oops. I did not know that, although I should have. It's sitting at work, running overnight, hopefully.

    I have already performed my routine:

    1. Damn, the TiVo's dead again.
    2. I will now reboot it in the futile hope it will work. Damn.
    3. I will now furiously poke manufacturer codes at it.
    4. I will now wait 24 hours.
    5. During that 24 hours, I will scour ebay for dirt cheap TiVos with lifetime subscriptions, bum around weaknees, briefly contemplate MythTV, look at TiVo for loopholes that will allow me to get a Tivo for nothing.
    6. Then I will bemoan the fact that we've lost everything and it will cost a fortune to watch TV again.
    7. Then I'll try the manufacturer codes.
    8. Rinse, repeat.

    OK, dd_rhelp stopped sometime in the middle of the night, so I plopped the new drive back into the TiVo with the old B drive (without making a backup of the B drive... you know where this is going). It went to the green screen pretty quickly (first time I've seen this), which I kind of expected. Here's my concern. If the copy didn't complete (substantially), and the TiVo rebuilds itself with the green screen, do I lose all the programs, including the B drive? If it doesn't complete successfully, but I'm able to get a good copy of the old A drive to the new A drive, will the B drive still work?

    you really need to dd_rescue to complete before re-indexing the drives in the TiVo. You need all the partitions for the recovery routines to work correctly.

    Looking at the instructions dd_rhelp is suposed to be able to start where it left off.

    So I should unplug the TiVo and try another re-image? I'm nervous about killing it in the middle of a green screen.

    Yup, it killed almost all of my recordings. They're still listed, but nothing's there. Do you think i can try it again, or is it gone?

    Sure try again what have you got to loose. Make the small truncated backup image from the currently working drives first. Then if the re-copy does not work you can go to the single drive configuration.

    Put it out of its misery and start fresh. You will be happier in the end. I lost 400gb of recordings about 10 days ago. I too was trying to recover using backups/copies/GSOD/FSCK and eventually killed my A drive to the point it wont even spinup or detect on the computer.

    Source a clean image and backup your var+etc directory from the old Tivo then throw the failing drive away.

    I previously had every episode of Mythbusters, every episode of Good Eats, every episode of Iron chef and half the episodes of Enterprise.

    If I use the old/new A drive and the old B drive, and then do an mfslive A+B consolidation (losing recordings) to a new large A drive, do I also lose season passes, preferences, etc?

    The backup made to a file on a mounted FAT32 drive backup -f 9999 -qso - /dev/hd? /dev/hd? /mnt/fat32/MyTiVo.bak Should keep the settings, season passes and wish lists. your recordings will still appear in the index when you restore the backup file image to the drive. You then need to manually purge them, they won't play anyway.


    In the future if you want to double your chances sign up to KidZone or GuruGuides both have the side effect of backing up your information.

    no, just recordings... you should have done a backup like that BEFORE playing around with these thing, BTW

    Playing around with these things, as you say, was trying to recover from a bad drive. I have an older backup from about a year or two ago somewhere around here. Getting the backup of the screwed up drive seems to have done no good--the bad block's in the OS. So I used the semi-recovered drive+B, which boots fine itself, but the restored, new drive didn't work. Gaaaaaah. I'll try the old backup image.


    From 2003.

    If you can get the system to boot with the "bad" copy perhaps you could use TivoWebPlus to save a backup of your season passes before starting fresh?

    keeping in mind that you can't RESTORE SP backups on s/w versions 6.3 or >8.1 (not 100% sure when they added the extra field in 8.x)... problem is that it WILL restore, but it'll break the tivo (at least temporarily... just like creating SPs with older TWPs).

    Chebeague...
    You may be too far gone to want to try this with your old drives, but I had the exact same problem with my S1 SA a few years ago. Twice in one month, my TiVo rebooted every four minutes. After replacing the drives and power supply, I discovered that it needed to run a Clear and Delete which would clear all the corrupted guide information, but not the recorded programs. A daily call was then required to reload everything -- a total of about four hours. So I wrote a routine into hackman that checks the boot frequency and if the box has rebooted more than five times in the past hour, it will initiate a Clear and Delete followed by a Daily Call.

    I was criticized for treating the symptoms but not the disease, but since I didn't know how to cure the disease, this fix worked for me. Still does, by the way, as it still happens now and then.

    Yup, I'm going with a single, 320 GB drive (on sale this week!), once I actually get over to Compusa to exchange drives...

    I've confirmed that the image from 2003 works (it's upgrading right now, I just want to make sure that goes through), but obviously it's got screwy season passes and preferences (it's still recording Mash instead of Good Eats on recommendations...) Is that /var/whatever it was where TiVo stores this stuff, and can I transfer it from the semi-working dual drive setup to the new single drive setup to recover the modern (2007) settings?
