    I tested using JMFS on the TP and doing a C&E more than once.

    The stock TP has 14 partitions.

    1 : start= 1, size= 63 ( 31.50K), type='Apple_partition_map', name='Apple'
    13: start= 64, size= 343828320 (163.95G), type='MFS' , name='MFS media region 2'
    2 : start= 343828384, size= 1 (512.00b), type='Image' , name='Bootstrap 1'
    3 : start= 343828385, size= 16384 ( 8.00M), type='Image' , name='Kernel 1'
    4 : start= 343844769, size= 524288 (256.00M), type='Ext2' , name='Root 1'
    5 : start= 344369057, size= 1 (512.00b), type='Image' , name='Bootstrap 2'
    6 : start= 344369058, size= 16384 ( 8.00M), type='Image' , name='Kernel 2'
    7 : start= 344385442, size= 524288 (256.00M), type='Ext2' , name='Root 2'
    8 : start= 344909730, size= 262144 (128.00M), type='Swap' , name='Linux swap'
    9 : start= 345171874, size= 1048576 (512.00M), type='Ext2' , name='/var'
    14: start= 346220450, size= 6291456 ( 3.00G), type='Ext2' , name='SQLite'
    10: start= 352511906, size= 1638400 (800.00M), type='MFS' , name='MFS application region'
    12: start= 354150306, size= 1638400 (800.00M), type='MFS' , name='MFS application region 2'
    11: start= 355788706, size= 269353742 (128.44G), type='MFS' , name='MFS media region'


    JMFS will create 1 new partition when it expands a drive. So, yes you can expand from a 320G to 1.5TB then C&E to a 2TB using JMFS.

    Anything over 16 partitions are seen as an external storage and you will have to run the divorce. AND the TP will go back to whatever the source drive size was.

    Wluk,

    I'd drop that 2tb drive in windows and delete any existing partitons and try it again. You may even want to first run WD diags against the drive to make sure it is not the problem.

    Sad to say I never encountered any errors in my testing of JMFS.

    there are 15 partitions on the 1.5tb drive if I read it correctly. does it mean I still have a chance to expand the 2tb drive.

    the 2tb WD EARS drive only had 1 partition before. But I will take your suggestion and try deleting all partitions form windows then run the wd util and try it again tonight.

    Need to put the 1.5tb drive back before tonight or my family will kill me.

    Sounds like a plan.

    When you try this again.... just do the copy only. Plug the 2TB back in the TP and make sure it boots up.

    Then you do the expand and test it in the TP again.

    And lastly do the supersize and see what happens then.

    fdisk -l reporting the 2TB as a GPT partition is strange to say the least. I don't enough about MFS or JMFS to explain that one!

    good luck

    I was able to convert my drive from GPT to MBR. Now when I run fdisk -l, I don't get the GPT warning.

    Will run the copy tonight and see what happen.

    ok..I was able to restore the original tivo image using dd for windows to the 2tb WD EARS drive.

    When I tried to expand it, now I am getting

    MfsAdd exception: Disk '/dev/sda' does not contain partition '/dev/sda15'

    I chmod the disk but still got the same error.

    Thanks. I will try it again after I copied the data from corrupted drive to new drive. If I can get kickstart to work, it will have a much better chance to repair the new drive (with corrupt data from old drive).

    Before reporting status of my rescue effort, here's a summarize of my situation so far: My comer'ed 2TB TiVo Premiere is stuck in reboot loop continuously. WD diags tool reported S.M.A.R.T. failure, I got a replacement WD20EVDS today and attempt to save my recordings.

    wdidle3 disabled the timer of the new drive, and now jmfs is copying from defective 2TB to the new 2TB. Based on current 1500MB/s rate, it would take more than 2 weeks to finish the copy! That is insane, not sure if can live that long before my family kills me :)

    I understand jmfs is designed to copy from stock drive to a larger drive, would copy from 2TB to 2TB work and preserve expanded/supersized partition? (I suppose I should only use Copy function, without touching expand/supersize functions since it was already done on the old drive)? If I am to wait for 2 weeks for the copy to finish, I better make sure this approach will work.

    any alternative way to do this? how about dd_rescue from MFSLive? mfslive.org never mentioned TiVo Premiere, so does it even work with Premiere?

    I suspect that may have been because the EARS drive is an "advanced format" one.

    I don't know of anybody's version of fdisk that'll show you TiVo partitions, but it looks like your drive was set up for Windows partitioning at some time even if actual partitions weren't written to it. Maybe it comes that way from WD.

    To see TiVo partitions, use pdisk.

    I was able to get rid of the GPT warning by converting it to MBR in windows.

    Anyway, I did the copy again last night after converted to MBR but still doesn't expand.

    Luckily, I still have the original 320gb image backed up with dd last year. I was able to restore it with dd for windows with multiple tries. You can't restore to any partition it has to be on the volume of the drive.

    Once I got the image restored, Tivo asked me to remove the expansion partition or something like that. After that I was able to expand and supersize it.

    I spent much of the time today to backup the videos from the 1.5tb and will load all the videos back to the 2tb. Even though I couldn't get all the videos backup, at least I have 317 hrs HD recording time on my tivo.

    Thanks guys.

    Just realized that jmfs in fact uses dd_rescue to copy the drive so never mind. Will have my fingers crossed for the next 2 weeks. It is unclear to me what data is corrupted, I only hope it will not prevent me from boot from the new drive. I will not know until 2 weeks later.

    Anyone know why dd_rescue is so much slower than common Windows disk imaging software like Norton Ghost or Acronis TrueImage?

    dd is sector by sector, including the "empty" space. IIRC, Ghost can do that, but typically is used with compressed images, copying only what is referenced by the partition table.

    I'm assuming your drives are using direct SATA connections, and not a USB/SATA drive dock. That would seriously bog down the transfer.

    Well, but 2 weeks for 2TB still seems to be unusually slow. Although I haven't tried to clone 2TB in Windows, based on past experience it may be a few days max.

    Yes, I connected both drives to motherboard SATA ports. dd_rescue shows avg transfer rate is 1420 kB/s, a far cry from SATA 3Gbps limit. Maybe the linux distribution used by jmfs does not have proper SATA driver?

    You're not on an old PC doing this, are you? I use an ancient Pentium III for my copying. It's slow, but it gets there.

    Also, dd_rescue goes slower on the corrupt parts of the drive. Your instant throughput may actually drop when it gets to the bad parts.

    I am using my HTPC with i3-2100 3.1Ghz on ASUS P8H67-M EVO motherboard, it is quite new. Now here's what's get interesting. I switched to an ancient PC - AMD Athlon XP 2100, connecting drives via USB dock and adapter, and start over again. Now the speed is showing 2075 kB/s (vs 1420), a slight improvement. so It will took slight less than 2 weeks still :(

    Good point on dd_rescue slows down on bad sectors. from what I read, it should proceed with full speed until find bad sectors. however it shows 0 errors on both PCs. Maybe SMART failure triggered the slower mode for the entire drive?

    Since you've tried 2 different MB's then would it be safe to assume it it is not a JMFS driver problem?

    And might one assume you used the SATA ports on the ASUS board?

    If you still have the stock drive try copying that one as the source and see what speed you get.

    Another thing to consider is that dock and adapter USB 2.0 and SATA II compliant?

    If not then that just slows things down even more.

    Just out of curiosity....

    Right now I'm copying from the stock 320G to a 1TB eads (don't have a spare 2TB) using 1 sata port and a Thermaltake Blackx dock to a USB 2.0 port and the average rate so far is 30123 kB/sec.

    This is on an ASROCK P43DE MB, 2 Gig ram. Q6600 cpu.

    I agree.

    Yes

    Thanks for the suggestion. In my eagerness of getting TiVo back in order, I missed the obvious. Tried this on the Athlon XP 2100, copying from stock drive to new 2TB, it shows 14,000 kB/s! so I guess the defective drive is the cause.

    Yes.


    Once I hooked up the defective 2TB, copy rate slowed down again. So finally I narrowed down the cause to the defective drive itself. this time, it is even slower: only 800 kB/s! :confused: The crazy thing is, it is because I lay the drive on the table with label side up. Once I flip the drive to label side down (after power down of course), the rate went back up to 2000 kB/s :eek:. This is way over my head.

    Even if you were ever able to get a complete copy, I would doubt it would even work since you are copying corrupted data to the new drive.

    If it were me I'd bite the bullet and just do the copy and expand and supersize from the stock drive.

    I am hoping the corruption did not affect critical data. So far, dd_rescue shows 0 error count, so I am hopeful. Even if I cannot boot from new drive, I still have kickstart to try, which will have a much better chance of success on the new drive. Old drive has too many recordings for me to give up early.

    I upgraded by premiere (DVR Dude) to a 2tb drive. Now I would like to create a backup hard drive. Anyone have an idea of the easiest way to do this? Would simple backup software successfully achieve this (I currently use Paragon)?
