While it is true that the Samsung Data Migration program (designed specifically for Samsung SSDs) presumably does have capability of excluding data from the source disk during the disk-cloning process it's not as simple a process as we would like. There's no clear-cut option to instruct the data migration program to, for example, "Transfer only all the files necessary for creating a viable OS on the destination disk." (If only there was such an option!
Virtually all of the users I've spoken to who have tried to use the SDM program for this purpose have pretty much abandoned that process and ultimately fresh-installed the OS onto their new Samsung SSD and then manually reinstalled whatever programs could "fit" on the SSD and manually transferred other data.
I would be interested in learning if you PERSONALLY have been successful in using the SDM program for this specific purpose.
From the samsung SSD white paper:
"The first partition, which generally contains the Windows operating system installation, is added automatically. Users can add an additional partition to the migration by simply clicking on its picture."
So if you have a partition dedicated to the OS files, you can opt to only transfer that partition, and leave the rest on the initial drive.
SDM 2.0 also supports custom cloning, not sure how long ago this was released, but it allows you to select/deselect individual files to be cloned:
"In most cases, PC users use 500GB, 1TB and even more capacity of HDDs while SSD is less than that. If you (...) want to migrate your data from your 1TB HDD(500GB used) to a 250GB SSD, you’ll find that the Target Disk(SSD) is not large enough to accommodate all files on the Source Disk(HDD). “Custom Cloning” feature will help you select unnecessary media files on the Source Disk to exclude from the cloning process."
But you're correct, there is no clear cut option to specifically transfer ONLY the files required for the OS to function, unless you have set up a partition dedicated to that purpose previously.
Would be an extremely useful function to have!
