    Just checked a 750500 image and it is also 4k aligned. So it appears all the 4 tuner premieres are 4k aligned. FWIW. The partition tables are still using 512mb blocks. If someone was real adventurous, they could dissect the ext partitions to see if they use 4k clusters. If they do, then it would imply that being 4k aligned has more meaning.

    I never pressed the triangle with the exclamation point on a post so I do not know what carnage ensues once someone does press it. Wonder if someone accidentally pressed it and the post got deleted. :eek: I guess I could make a post and try it. :confused: Afraid someone might come to my house and confiscate my computer if I do. :p

    This is as I have been suspecting... 2-tuner: no alignment (unsure if a software update can align), 4-tuner: factory aligned (possibly, or capable with a software update).

    For those with the time to play around:

    1. Make sure your TiVo has 2 hours, that it won't be busy.

    2. From LiveTV mode: Press 911, then rapidly hit clear (so channel doesn't actually change).

    3. Reboot, do a kickstart 52 (emergency software reinstall).

    4. As soon as you can get back to LiveTV, repeat the 911-clear.

    5. Go to System Information screen: Press Clear, Clear, Enter, Enter, Zero.

    6. View the system logs (I suggest not messing with the other items in the backdoor screen), using the right arrow to change through the logs, Up & down to scroll, and look for the 911 markers in the logs.

    7. When you find the log with loads of info about the filesystem, find the top 911 marker, and you'll get your drive model, capabilities, modes, drive state, sector size, clusters/blocks.

    8. Scroll through until you've reviewed to the second 911-clear marker, and take notes of anything you feel is relevant.

    9. Report back here with your model, number of tuners, model and capacity of drive, and what the file system is/isn't doing.

    I think this is where we prove what's going on with what in the 512/4K/alignment matter, and there may be some competing theories as to what the future may or may not bring (like 4K alignment).

    The KS 52 does a full assessment of the drive and the file system, before copying the current software to the alternate partition. It's also far less likely to brick your unit than a KS 57 or 58, if (when) repairs and cleanup operations are performed on the file system.

    * All 911-clear does is put a one-line marker stamp in the logs, so you can find what you're looking for faster/easier

    I thought KS 52 was "Emergency Software Reinstall".

    How to download screens using the jmfs software.
    1. Have a HPFS or FAT disk attached together with your Tivo disk. Harddrive or USB.
    2. Boot jmfs
    3. Exit to shell (x)
    4. Run fdisk -l. Check the HPFS/FAT partition names, it has to have a number after disk name, like:
    Code:
    
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1               1      194522  1562497933+  HPFS
    
    5. Create directory: mkdir mydisk
    6. Mount the partition on which you want to copy the log (akin to "assign drive letter" in Windows). If it is HPFS, then you need to specify the driver to use (the default one is read-only). No need to do it for FAT. For HPFS: mount -t ntfs-3g /dev/<partiton name> mydisk (for example: "mount -t ntfs-3g /dev/sda1 mydisk")
    For FAT: mount /dev/<partiton name> mydisk (for example: "mount /dev/sda1 mydisk")
    6. Run "/root/mfslayout.sh /dev/<partition name>" and see if you get the correct output on the screen. If so, then run "/root/mfslayout.sh /dev/<partition name> > filename" of your choosing. This pipes the screen output to that file. Then run "cp filename mydisk/" (it will copy the log to the root directory of the given partition).
    7. Unmount partition (just a precaution, so all the buffers are flushed and file system is clean): umount mydisk

    It is, but it runs VERY thorough file system checks, has NEVER nuked a TiVo (like a 57 or 58 has done to me from time to time), and logs more data than the other two combined.

    Think about it: The last thing TiVo wants is to nuke a unit into the GSOD reboot loop when sending out updates, so It checks, cleans, and defrags the file system of the alternate software partition FIRST, and logs more data, just in case an update does nuke a unit.

    One bit of misinformation I've seen floating around here from time to time, is that KS52 installs the previous software version - absolutely false.

    I found the "extreme logging" that happens on a software install/re-install by accident.

    I did update my post, figuring that if I didn't specify what KS52 was, questions would pop up.

    The only danger, is if there's an unidentified bad sector on the alternate partition, but that would hit you on the next software update anyway, since every update switches to the other of the two partitions. If that worries anybody, then run the full battery of SMART tests first (under KS54).

    You might want to make it clear that <partition name> in the second step 6 (you have 2) refers to the TiVo drive and is not the same as <partition name> in the first step 6. Actually, shouldn't it be a device (ex.: /dev/sdb) rather than a partition in the second step 6?

    Minor, somewhat geeky correction: You are not "piping" the output, you are re-directing it.

    On a lighter note, anyone ever see the mfslayouts in concert? :D

    I doubt that they need MFS lessons from me. :D

    Que Sera, Sera. Now back to our regularly-scheduled thread.

    Dang this :eek:

    I just bought HP ENVY H8-1450 Desktop which as a Gigabyte card. So is this mostly a single or small amount of Mother Boards or is it all known Gigabyte boards?

    I feel better now with a bit more research. will need to look into bios and check sata position of drives, I wondering if putting the caching SSD in sata0/1 would be ok.

    I just received a shipment of six WD20EADS-00S2B0 HARCHV2AA 2TB Western Digital hard drives, as replacements for some degraded/defective ones I sent back. They're factory recertified replacements, still sealed.

    PM me if you'd like to make me an offer. If you'd like, I could pre-image them for either TiVo HD, or 2-tuner Premiere. I don't need them, because I already bought EURS AV-GP replacements, when Newegg had them on special.

    I know some don't like/trust 4K drives, so I figured these 512-byte sector ones may be of interest to some of you.

    Does anybody know if the WD20EURS has intellipark enabled?

    Straight from the factory, it is enabled. You can disable it (with a tool called WDIDLE3.exe), if it causes you to hang on the boot screen after a menu reboot (warm reboot, versus a "cold" power-cord-pull-boot).

    I've heard that something with the firmware of the WDEURS, implemented a while back, stops that from happening. But, it used to be an issue with any Green drive from WD, unless manually disabled.

    ALL GreenPower WD drives have the intellipark feature, even if they are advertised for 24/7 video usage.

    I haven't seen recent posts reporting an issue with the warm boot hang, for quite some time. So, either TiVo and/or WD have fixed that, or those that encounter it find the many posts on here that say how to disable it.

    I've seen a FEW, *old* reports that a full disable can cause strange behavior, but increasing the idle timeout to 300 seconds, instead of 3, didn't cause those issues, and achieved the ability to not get hung on a warm reboot. So, that's how I've been setting mine, when setting up a new drive.

    The new WD20EURS that I bought from Amazon last August did *not* have Intellipark enabled which I verified by checking with WDIDL3. I used this successfully in an TiVo HD that I had picked up for my son for college.

    I guess they must have come to their senses and realized that a 24/7 rated drive shouldn't need it, if used for the *primary* target market. Also, since TiVo uses those drives in their 2TB models, they might've been inclined to disable it, since they do market it for non-surveillance DVR use as well. I could see applications where people might use the drive for AV streaming non-24/7 run-time, and it'd make sense to use it, but that's a minority scenario. I've seen mixed reports, so I erred on the side of caution...

    Thanks for clearing that up.

    So I've tried reading through this entire thread (and believe me it was long) but I'm trying to find a solution to upgrade my TiVo Premiere drive using only one USB to SATA device. Is there a way to make an image of one of the drive then restore it to another drive without doing a direct copy with both drives attached?

    BTW, USB<->SATA devices are readily $15 and under nowadays.. So it really isn't TOO much of a burden to get another. I mean just the "cable + power" things to use a bare drive.

    My TiVO drive was already upgraded to a 1TB, and started making noise and the TiVo rebooted quite often. So, I unplugged it, and ordered a new disk. I'm now attempting to copy the original disk (hopefully it works enough to do so) to the new disk.

    It seems to be going VERY VERY slowly. Average rate: 240kB/s.

    This is going to take an eternity! Is there a way to just copy the OS to the new disk for the Premiere? I honestly don't care about the programming content.

    Use DvrBARS and do a truncated backup followed by restore.
