    Replacing a failing hard drive in my TiVo Premiere. It's so far gone that I have to borrow a drive. That means lugging a PC to my Mom's and tearing her Premiere apart and copying her drive to a new one.

    I have several PCs available for the job. And I don't want to spend 30 hours over there.

    So, if I take a fast PC (i.e. Core i7, etc.) vs a slow PC (Pentium 4 3.4GHz) will the transfer speed be affected?

    Also, how long would the copy process take approximately?

    It depends on the sizes of the hard drives. The bigger the drives, the longer it takes. Somewhere in this forum I think I've seen a thread talking about typical transfer speeds but it can take a lot of hours for 1TB or larger drives. As for PC selection, you should be able to do the copying without tearing open the PC. I always use cheap USB to IDE/SATA adapter cables and can run the imaging software from my laptop, if need be.

    I have upgraded with content and it took nearly 24 hours using an i3. Without any content it only took a few hours, started at night and done by morning.

    FYI- I used an USB-SATA connection for one of the drives, which had a material impact on the speed.

    Time:

    The TP 320G directly connected to SATA ports on MB around 3 hours.
    The TPXL 1T directly connected to SATA ports on MB around 7 hours.

    Using USB-SATA cabling double the above times.

    JMFS does a byte-for-byte copy, there is no option to copy just content.

    The above was using an old P4 several years ago. I would like to think a newer computer would be faster.

    BUT, if there are read errors on the existing TIVO drive it will take forever to copy. JMFS tries 3 times to read a 512 byte sector before it gives up and goes on.

    Do any of the PCs available have a GigaByte brand motherboard?

    If so, don't use it.

    It could even hose your mom's Premiere's drive, depending on how the drives are hooked up.

    If she has the stock 320GB drive, then if you happen to use jmfs and both drives are connected to SATA ports on the PC motherboard, this post

    indicates that you're looking at around 3 hours for the "Xerox" part of the process.

    Of course

    dd_rescue

    on the MFS Live cd will probably take about the same amount of time as

    ddrescue

    which I think is what jmfs uses.

    You can copy mom's drive to another one with either of those programs, or even with the original

    dd


    and then later, back home, copy the copy to another drive.

    The original copy will think that it's a 320GB drive because the bootpage and partion map will have been copied as well as all of the original partitions at their original sizes.

    Well then I'm not too concerned about my original question then. My powerhouse PC with the i7 has a Gigabyte motherboard :(

    I'll just use an older Dell desktop and let it run.

    I don't know if every GigaByte brand motherboard ever made does it, but apparently the majority of the ones over the past decade have a tendency to put Host Protected Areas on at least what the computer thinks is or is going to be the boot hard drive--something about a place to back up the BIOS or the CMOS or the boot files or something, but it just goes and does it without warning and there's no way to disable its ability to do so.

    And in order to undo it you have to move the drive to a different brand motherboard.

    Just as a point of reference, I clone my desktop hard drive now and then as a backup using Clonezilla (Linux SW) and an external USB drive. For 500GB it takes about 4 hours on a 2.4Ghz Core2 Duo.
