    Hacking HDTV Tivo forum (HR10-250)

    now that we are starting to receive our HDTV Directivo's, is there any way we could have a forum section dedicated to hacking the HR10-250's?

    when you actually receive your unit, please let us know. we need, among other things, detailed photos of the inside. as for a new section - based on the information i have gotten, i dont see any real need for a new section.

    things to do when you recieve your HR10-250

    BEFORE you even plug it in:

    (be sure to boot from a knoppix cd or other lba48 kernel for these)

    get a 300 gig hd (or identical 250)
    make a mfstools backup of the original drive
    restore it to the new drive
    see if the HR10 will boot from the new drive

    make a DD copy "dd if=/dev/hda of=/dev/hdc" (with original on primary master & clone on secondary master)
    see if the HR10 will boot

    check the original drive bootpage settings with "bootpage -p /dev/hdc"

    check the original drive partition layout with "pdisk -l /dev/hdc"

    make dd copies of the partitons 1-7 & 9

    dd if=/dev/hdc1 of=hdc1.dd


    might as well try sleeper's iso on the copy while you're at it

    Any other things to try out?

    I am getting my unit tomorrow. Can use a 120 gig seagate drive instead of the 250 or greater hard drive?

    Its just more difficult to go to a smaller drive and not all the tests that were listed will work going to a smaller drive.

    HDVR2 - 120hours - Extraction enabled
    SD-DVR40 - Unhacked (for now)

    Ok, looks like I'll have to make a trip and buy a 250 gig drive.

    oh well.

    Here is the so-called "upgrade thread" for HD TiVos at TCF:

    http://www.tivocommunity.com/tivo-vb...hreadid=171445

    Not surprisingly it only focuses on adding a larger drive, since that is pretty much the only thing that that happens in the "TiVo Underground" anymore.

    From this and from the pictures, we can tell:

    - the partition layout, bootpage, major MFS structures, etc. have not changed
    - the ATA password stuff we see in some S2 PROMs was not used to lock the drive
    - the PROM is a plain old user-friendly PLCC, not something nasty like a BGA
    - the drive is not SATA

    More and more, it sounds like the HD units are really just overhyped cousins of the HDVR2, not the major overhaul that many of us expected.

    Would someone be kind enough to either publicly or privately get us a copy of the dd'd drive image?

    Sure not a problem, I am not an expert in linux, but if you post the commands. I'll be more than happy to do that for you.

    Code:
    dd if=/dev/hdX bs=2M | gzip -9 > /directory/and/name/of/file.img.gz
    Where hdX is the IDE bus that your tivo drive is located (a, b, c, d.) This will take a long time, so be prepared. Also, if you have used this tivo to record anything (and even deleted it,) or simply just watched livetv for a few minutes, expect this image to be very large. This method will only be feasable if you haven't actually booted this drive in your tivo yet.

    Before PMing me: Iím not your personal tech support. If you have a question, ask in public so I don't have to repeat if somebody else asks. If you want images or slices, use emule. I will ignore all support PMs.

    Sponsor a vegetarian! I have taken the pledge, how about you?

    Hr10-250

    I've just got my HR10-250 yesterday.

    I did a "mfsbackup -f 9999 -6so /mnt/c/hdvirg.bak /dev/hdc" before I booted the machine and have that image.

    I don't have another 250gb drive to work with but have a 120gb drive.

    The unit is now up and running so no longer "virgin".

    Willing to work with what I can to help.

    Email or PM.

    dd doesn't need to be slow.... thankfully!

    Making the block size bigger does help speed. It also helps if you
    Code:
    hdparm -d1 /dev/hda /dev/hdc
    to turn on dma on those drives (in this case hda and hdc, change for your configuration). In addition, if you put the infile drive and the outfile drive on different ide cables (primary and secondary) you will see some improvement. I dd'd an 80GB Tivo drive last night and it took 65 minutes. Not too bad, as I had read elsewhere here that it would take 14 hours! Glad it didn't.

    The original drive is a a Western Digital WD2500. (488397168 Sectors) I'm going to dd the image onto a Maxtor L01P250 which is 490234752 Sectors. I don't think it's necessary, but I'm going to use MaxBlast III and set the BIOS to report the same size as the WD drive before dd'ing the image.
