    I am stuck trying to upgrade, hope the TiVo experts here can help. I got a WD30EURX and am trying to put it in a 750500. I have been able to transfer the image off using DVRBars (Thank you ggieseke) and put it on the WD30EURX. I can put it in the TiVo and it works. My problem comes when trying to expand and supersize it. JMFS won't recognize the drive when I boot it. It will recognize all the other drives I connect. I don't have a desktop so I'm using a SATA to USB adapter. Also, I have a clean image of the 750500 that has never been plugged in. If it is needed I just need to know where to send it. I would appreciate it if someone could share an image of a 74632. I hosed it up and had the wrong hard drive connected and mounted it in disk manager. I have no need to try and save the recordings at all. Any help from the TiVo gurus out there would be appreciated.

    Well if you are wanting to use the whole 3TB drive you well have to do more than just use JMFS. The best you can do is about 2.1TB over your base image size. If you want to be able to use the whole 3TB, we can guide you through it. Read the 4TB DIY thread for background.

    I did read that thread, my understanding is that before I could even start that process I had to get it expanded to the 2TB. I can't get that far, the JMFS won't recognize my hard drive. Is there any way to expand the drive without JMFS?

    I'm running an HP Elitebook 8460p, it has a Intel Core i5 vPro, with a Mobile Intel QM67 Express Chipset. I'm using the JMFS Live v 1.04. It just won't recognize drive. I can get it to recognize any other drive I put in. It works fine in the TiVo, it just sees it as a 500 gb drive. I'm trying to find a desktop so I can try it with it plugged in directly to a SATA port on the mb but haven't had any luck so far. I couldn't PM you back since I don't have enough posts but I have a 750500 vhd from an out of the box system that's never been plugged in. I'm downloading the vhd, is that an already expanded image or just stock? Do you have a vhd for a 746320? I have another TiVo drive that I toasted when I accidentally mounted it in disk manager and I wanted to have it around for a just in case backup. (I thought I had my 3 tb drive connected) Thank you for your help.

    You are using an external dock to connect it to the HP. Is it connected via a USB2 or USB3. I have problems using USB3 with JMFS with my systems so I only use it with USB2. Are you booting the CD or are you running the CD in a virtual PC inside windows.

    We probably need to carry this conversation over to the JMFS thread as we are getting off topic here and this is something that will take a little time to sort out. So post your reply to the JMFS thread and we will go from there.

    In general, people should be aware that the current crop of USB 3 controllers are mostly NOT supported by the machine's BIOS the way USB 2 controllers are, whether desktop or laptop.

    What this means is that drivers need to be loaded to see the USB 3 ports, whether in Windows, or a compiled Unix bootable distro. Without a loaded driver, most USB 3 ports are not there.

    Greg (ggieseke),
    I recently had a TCD748000 die and I don't have a backup image.
    Can you send me the link by PM to download your virgin backup?
    I'd send you a PM but the forum won't let me because my account is too new.

    Thanks!
    -Jerry

    I hope someone can shed some light on my observations.

    1. 3.5 year old TiVo encounters GSOD. Initial indications are disk problems. Tired to run Kickstart codes to fix it. But nothing worked. Initially I could launch KS 54 to test the disk (which found no errors). But after running KS 57, I could no longer launch KS54. System went into reboot cycle: Welcome, Almost There..., GSOD.

    2. I got this error message when I try to do a backup using DvrBARS:

    MFS volume header not found
    (should have run JMFS Live advanced options, but didn't learn about it until I'd wiped the disk with a restore)

    3. Ran extensive diagnostics on disk with HD Tune Pro and ran read, write, seek and performance tests. None, zero, nada, errors are found with any test. No test result was out of spec. S.M.A.R.T. shows no reallocated sectors. No other errors found of any kind.

    3. Got a new disk from WK (could have come here first to get image, maybe). Backed up image from WK disk with DvrBars and restored it to the original drive.

    4. Drive seems fully functional now.

    Questions:
    1. What could have happened to the disk to cause this?
    2. Is it known, or possible that TiVo's OS has serious problems where it can trash the structure of the disk?
    3. Are there ways, restart, clean or other operations that can be used to avoid this?
    4. Has anyone else encountered this or thinks they have?

    Thanks,
    John

    Hey John,

    I replied in your other thread, but I'll try to combine the two here. You're not the first person to have KS57 take a marginal drive to unusable. Without the source code we'll never know for sure what the Kickstart codes do, and TiVo isn't likely to give us that info.

    My last attempt to repair a drive that didn't have a recognizable MFS volume header went south when the original poster gave up (or just quit responding).

    1. Good question.
    2. Another good question.
    3. Not that I know of.
    4. Probably several people.

    I think it's fairly clear that you had an OS or filesystem meltdown that wasn't caused by a hard disk failure, but sometimes bad sh*t happens to good people.

    If you want to attempt a recovery I'm there for you. That would probably mean shipping the drive to Houston, but at least we both have the same hardware (Premiere XL). If it's salvagaeble I'll do my best.

    Greg

    My guess when things like this happens, that there might be a power glitch during a disk write or possibly a buffer overflow problem. No one really knows for sure. Like Greg said bad things happen.

    Well, this feels like a serious OS problem. I wonder how many non-technical people had failures like this that really weren't a hardware failure. I did finally encounter a logged error of one bad sector on a write then read of all zeros across the whole drive.

    I wonder if TiVo knows or cares that there appears to be this serious problem.

    As I posted, I decided to bite the bullet and not attempt a recovery, this time. I just wanted to get the thing up and running. I restored the WK image to the original disk and we'll see how long it runs. Next time I'll take a closer look at it.

    Thanks for the info. You guys have done some amazing work with little, if any, internal info to go by. If it wasn't for all your collective work, and Weaknees, I would not have been able to fix this.

    I'm trying Dvrbars for the first time in attempting to backup a 320gb drive out of Preimere.

    I'm receiving "ReadFile" errors about every 40-60 seconds and the after 30 minutes, the progress bar hasn't moved.

    What does this imply?

    The drive it's self appears good, Smart disk diagnostics and WD short test passed with no issue. Also, does it matter if ACHI mode is enabled or should I use standard IDE mode for the PC controller?

    <<Edit>>

    Stopped the full backup since it didn't appear to be going any were and started a modified however it ended after I clicked OK....

    [​IMG]

    Any suggestions?

    AHCI mode is usually faster than standard IDE. Other than that it's a wash.

    If you click OK through enough of those errors you may still get a functional backup, but if it goes much beyond 10 or 20 clicks I'd probably give up and throw the drive in the trash.

    DvrBARS reads 2MB chunks at a time and wasn't designed to be a drive recovery tool, just a backup & restore utility for healthy drives. It doesn't even break drives down into 512 byte sectors like ddrescue, much less have any repair abilities like SpinRite.

    If you can get through the backup and restore it to a new drive it may work despite the bad sectors. If not, I can send you a link to a 746320 image and you can start over from scratch.

    IMO it sounds like your 320 is dead. :(

    I have another Premiere with 320Gb drive that is good, if I need the image I will let you know but otherwise I will see if I can make my own off what I have.

    I ran the extended WD tests on the drive and it failed with too many bad sectors so I gave up and I'm doing a full write of zeros across it to see if it as drive it's recoverable.

    You may be able to recover the drive but if sectors are already failing it is an accident waiting to happen.

    Could someone send me a link to the image for a 746320? I don't have enough post to PM.
    Thank you!
