      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

    Just having a play around, this turned out to be not as clear cut as expected.\n
    \n
    so I created a file and entered some text, used xxd to get the hex values, and then opened the device /dev/sdb1 in wxhexeditor and tried to find my file, but it’s not finding it. Inode is 19, so it should be right at the start of the first block group, but after several minutes, no joy. (drive is ext4.)\n
    \n
    I thought this was going to be an easy task, just multiply the inode by the block size, open the device with wxhexeditor, and scroll to the line corresponding to the calculated byte, copy out the hex values and convert to ascii and voila, there’s the ‘hello world’… except no.\n
    \n
    What am I missing here? Drive isn’t encrypted, nothing silly like that.\n
    \n
    Ok, I managed to do it with dd:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">sudo dd if=/dev/sdb1 bs=8M skip=$((4660742*4096)) iflag=skip_bytes | head -c 4096\n
    </span><span style="color:#323232;">\n
    </span><span style="color:#323232;">hello\n
    </span>\n
    ```\n
    \n
    but why can I not find it using wxhexeditor??\n
    \n
    EDIT:\n
    \n
    Duh, I didn’t click that offset needed to be multiplied by the block size.\n
    \n
    If I go to offset 4660742*4096=19090399232 in wxhexeditor, indeed I see the file contents:\n
    \n
    ![](https://files.catbox.moe/6zvhx0.png)\n
    \n
    Final conclusion:\n
    \n
    After some more testing, I have concluded: you cannot easily calculate the offset using the inode. Finding files across the disk requires using the inode tables to get the offset and actual file location. So an inode does not correlate with a physical/logical sequential disk location.\n
    \n
    I created a new file, it received inode 21, but the offset was smaller than inode 19.\n
    \n
    Was that a good use of 3 hours of my life? Well… I still have no idea what’s up with the Kardashians, so… I guess?

      Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).\n
      \n
      Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word “Linux” in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.\n

  +url: null
  +body: """
    Just having a play around, this turned out to be not as clear cut as expected.\n
    \n
    so I created a file and entered some text, used xxd to get the hex values, and then opened the device /dev/sdb1 in wxhexeditor and tried to find my file, but it’s not finding it. Inode is 19, so it should be right at the start of the first block group, but after several minutes, no joy. (drive is ext4.)\n
    \n
    I thought this was going to be an easy task, just multiply the inode by the block size, open the device with wxhexeditor, and scroll to the line corresponding to the calculated byte, copy out the hex values and convert to ascii and voila, there’s the ‘hello world’… except no.\n
    \n
    What am I missing here? Drive isn’t encrypted, nothing silly like that.\n
    \n
    Ok, I managed to do it with dd:\n
    \n
    ```\n
    \n
    <span style="color:#323232;">sudo dd if=/dev/sdb1 bs=8M skip=$((4660742*4096)) iflag=skip_bytes | head -c 4096\n
    </span><span style="color:#323232;">\n
    </span><span style="color:#323232;">hello\n
    </span>\n
    ```\n
    \n
    but why can I not find it using wxhexeditor??\n
    \n
    EDIT:\n
    \n
    Duh, I didn’t click that offset needed to be multiplied by the block size.\n
    \n
    If I go to offset 4660742*4096=19090399232 in wxhexeditor, indeed I see the file contents:\n
    \n
    ![](https://files.catbox.moe/6zvhx0.png)\n
    \n
    Final conclusion:\n
    \n
    After some more testing, I have concluded: you cannot easily calculate the offset using the inode. Finding files across the disk requires using the inode tables to get the offset and actual file location. So an inode does not correlate with a physical/logical sequential disk location.\n
    \n
    I created a new file, it received inode 21, but the offset was smaller than inode 19.\n
    \n
    Was that a good use of 3 hours of my life? Well… I still have no idea what’s up with the Kardashians, so… I guess?
