Linux
From Wikipedia, the free encyclopedia
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).
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.

Is it OK to simply dd the 128GB disk to the 32GB disk using count to stop after the 16GB partition was cloned?
I think it would work, but it seems a little overcomplicated, you can just use the partition paths as if and of of dd directly, as long as the output partition is not smaller than the input partition. For example dd if=/dev/sdc1 of=/dev/sdd1 bs=4M status=progress
Your method would also copy the partition table I suppose, which might be something you want under specific circumstances, but then it would be a little harder to get the count right, just taking the size of partition 1 would be wrong, because there is some space before it (where the partition table lives) and dd would start at 0. You'd need to add up the start position and the size of partition 1 instead.
Personally I would prefer making a new partition table on the new eMCC, and create a target partition on it. Then you clone the content of the partition (i.e. the file system). This way the file system UUID will still be the same, and the fstab should still work because these days it usually refers to mounts by filesystem UUID in my experience.
If you make the target partition larger than the source partition, and you intend to use the full partition going forward you will additionally need to resize the filesystem to fit the new larger partition, for example with resize2fs.
This is the way!
Way simpler than using any GUI tool or somehow recreating the partition and manually copying the files.
Dd with count does work. scroll down to: Use dd, with the count option. response

If I understand the problem correctly it has a pretty simple solution that I have done before. Make a new partition on the destination and dd if=/dev/diskAsB of=/dev/diskXsY where A is the source disk and B is the source partition and X is the destination disk and Y is the destination partition. You may have to run fsck on the destination afterwards and maybe a gpt repair tool.
Honestly though, since it's an ext filesystem, if it were me I'd just mount the source and dest and rsync.
Could be - just try it ig. And even if not, just create a new partition on the 32 GB disk and then dd it over.
Is the 16gb partition the first partition? If so I'd just dd the 128gb drive at the 32gb drive then fix the partition table and remove the others.
If it's not the first partition use gparted to copy it to the new drive.
Gnome-disk-utility or "disks" in Linux will clone a partition and then restore it to another disk.
@InFerNo@lemmy.ml you should do the partition not the whole disk. Then create a new partition in the 32gb disk or mount the dd file with a loopback device and transfer the files to the whole 32gb disk
It's a root fs for an ARM device. I can't simply copy the files over.
Is the system Linux? If so, then yes you can. Rsync it on to the newly created device get the uiid and fix up the fstab and boot loader configs and you are back in business.
