After running Clonzilla, looking at the M drive in File Explorer, it shows empty.

So did anything actually get cloned?
If so, where did it end up?


(I'm not familiar with Clonezilla...
https://www.clonezilla.org/)


Thinking ... what I would have done, would be to create a single, initial partition, sized the size you want your (cloned) C: drive.

450 GB or whatever.

Have Clonezilla clone to that partition.
Once that is done, & you're able to boot from it, then go back & create your other wanted partitions, sized as you wish, copying whatever data you need from the old into those newly created partitions.


(If Clonezilla allows you to just say, "clone existing c: to a new partition on 1TB, sized 450 GB", then I would do that, not even pre-creating anything on 1TB, i.e., just let Clonezilla do it.

And then again once Clonezilla did its thing, & you can boot from it, then go in & create your wanted partitions with the remainder of the 1TB space.)
